Harrop Eaton E Locker vs ARB Air Locker vs TJM Pro Locker Diff Locker REVIEW | ALLOFFROAD

[@marshiano]

Great Review. Thanks for a great insight into the options. I should have watched this before i entered blindly into buying a Harrop E-locker. my experience with Harrop E-locker is as follows. 1. They are a buggy and faulty item (a lot of dropped pins and mysterious "stuck locked" cases-(research for yourself before you buy) 2. Harrop customer care and warranty has to be the worst i have experienced as a consumer..They will blame anything with "could have been" "not defective" 3. My Harrop E-locker self locked on a freeway @90km/h (I have the fuse removed when not off-road) and not only destroyed the crown and pinion but also ripped out some of the front diff mounting on my ford Ranger. It was a horrific self destruction of a diff center that only ever had one off road engagement (just to try it) and under 1,500km since installation. 4. As the video shows the product isn't actually a locker unless you are moving forward they will unlock if you roll back (to adjust your approach.. which we all need to do) and will take ~1/2 a turn to re-lock ( how could this be called a locker?) It took Harrop more than a month to get back to me and refuse the warranty claim and they still haven't returned my diff back to me so i can have a mechanical engineer write a report. It has now been 2 months and i have had to purchase a new front diff assembly just to get the car back on the road. (I will be putting on an air locker as i will not do business with Harrop again) Please do your research and choose wisely

[@AlloffroadAu]

Wow, thanks for sharing that is bad, I’m so glad I removed my ones again

[@marshiano]

AllOffroad 4x4 Adventures TV Thanks for the pin. Purchasing on The perception of quality and simplicity was my mistake.

[@AlloffroadAu]

@@marshiano you were not the only one I made the same mistake. I could not find any useful information so thought I better make the video to hopefully save someone some coin and headache

[@efibendor1]

Sounds like you did a bad install

[@JAMESWUERTELE]

Forget the complexity check out OX locker. I’ve had an OX in a 60 since it was released for sale, in a F-350

[@seanpaddock9889]

Great explanation of all the lockers. I appreciate your honest transparent view. I was favouring the pro locker but after this detailed (very German 🙂) explanation of all 3, pro locker is the one I’m going to go with. Thanks for helping me decide. Great review.

[@AlloffroadAu]

Glad I could help, I believe TJM unfortunately discontinued the ProLocker I have now ARB installed by a Diff Specialist with 5 year warranty in the Hilux

[@bernicecanty721]

My fj cruiser has factory fitted rear locker electronic type and up front an arb air locker. Never had any issues and was installed professionally by outback 4x4 Bayswater. I do some fairly rugged inclines with ruts and rocks and poke along quietly up them with lockers on. Never miss a beat very happy indeed. I think front and rear is the way to go and know when and how to use and not use them. Excellent video.

[@Phil_McAvity]

Good video Stefan & I totally see your point. I just had soo many problems with my ARB air lockers that when I made the change (15 months ago) to the E-lockers it was almost magical, and haven’t had a problem in this time. But I can obviously see why you’ve changed.

[@AlloffroadAu]

yes mate, I hear you as well and I don't think E-Lockers are bad just not suitable for me, from my research it seems most people who have an issue with ARB's are because of poor installation and unfortunately I heard from a few people who had issues that they had them installed at ARB Francises which sometimes only have fitters...

[@ericandhismighty200lc5]

Thank you for the explanation i was convinced that elockers were the go for my 200 but thanks to your informative video im now going the tjm pro locker.

[@sherman4970]

Got front and rear ARB air lockers in my 91/92 Swb Pajero. Wanted them all my life,,,Very happy.!

[@juliangraziani7299]

I used to fit ARB lockers and can tell you they have quality issues. At the end I was dissassembling the locker and inspecting/cleaning the swarf from the units. TJM lockers are the best selectable locker on the market. E-Lockers are temperamental because of the way they lock and wiring in the housings actually move with the shaking which the housing goes through. I personally run a Lokka in the front of my part time 4x4 but nothing except the ramping type LSD in the rear. Im not into the crawling side of driving but I haven't been stuck without trying really hard.

[@gregj.gotham4402]

Thank you I was surprised how the E lockers work for real, my mind of air lockers just changed very positively. I’ve never heard of the TJM lockers but I’m going to research them this afternoon so I have the best for my 4X4. Not going rock climbing or hot rock bouncing, I’m building a rig for serious bug out and for running the old roads on my maps of the 20’s- 30’s I’m metal detecting old schools an homesteads in the mountains just want an all around 4x4 to tackle going where no one in 50 yrs has driven.

[@1davebreno]

Thanks for the time you've taken to put this together.

[@freedomrider266]

Much appreciation for your time, effort and willingness to do the research for OUR benefit...I am in the process of starting a long expedition throughout the western half of the country (United States) and I want to ensure that all my critical parts are of solid quality and durability. Again, thank you.

[@AlloffroadAu]

Sounds great mate enjoy your journey

[@TheTravelingTogetherJournal]

Thank you. I was one of the many who didn't know about the disengagement of the e-locker with direction change and that it would take a .25 rotation to engage in the first place. This will defiantly play into my locker buying decision as I drive a manual transmission and it is difficult to avoid a bit of rocking back and forth over obstacles.

[@AlloffroadAu]

yes you were not alone and even with an auto you may have sometimes non-deliberate but often deliberate small movement in reverse so for me I rather bee in full control of my locker

[@hendrikkarsten3784]

Thx for the great and accurate review. I personally have a ARB locker fitted for 10years in my Lux. I recently had to change a leaking air seal on the locker. It was a unpleasant exercise for small problem. Thx again for the useful info.

[@AlloffroadAu]

I reckon 10 years is good, bit annoying is that you take whole diff out and a 10c part cost $700 in labour

[@JAMESWUERTELE]

AllOffroad 4x4 Adventures TV sounds way more expensive to maintain than an OX locker

[@yorkbleyer9803]

Spot on review. It really comes down to your choice and what will work for your needs. In the end, failure of your locking diff, isn't an option. Awesome review!

[@AlloffroadAu]

Thanks for sharing

[@powderriver2424]

Just like any big purchase thorough research is needed, choose the wrong thing equals $3K or better mistake. None of these units are cheap, that’s including installation, I like the positive engagement of the pro- locker, however I never knew until now how all these functioned this was a very informative video.

[@AlloffroadAu]

Thank you very much....

[@bywayz]

I ran an ARB Air Locker in my 1990 Toyota 4Runner (5 spd, 22r-e) for about 25 years of daily town driving, wildland travel and occasional technical four-wheeling. While the sound and vibration of the compressor took getting used to, it never failed. I would buy another for my current '05 4Runner without hesitation if I still drove in conditions where it would be helpful.

[@s3uoq]

Just fitted a TJM Pro Locker to my rear diff after having originally wanting the e locker. Thanks for a great video and my installer reinforced my decision as he also agreed that its the best of the 3.

[@AlloffroadAu]

Great to hear!

[@GridLineGo]

Wow!! I didn't know the Elocker actually had a temporary disengagement like that. That is some great info! I've been doing a lot of research myself and thankfully came across your video. Thank you!

[@AlloffroadAu]

Glad I could help!

[@johnrogers5825]

This video would have to be one of the best on KZbin. Very professional. I think I am leaning toward TJM but not 100% sure. I sit on the fence deciding for so long that something new usually comes on the market. Lockers are so confusing to pick the right one; it is a pity there isn't one on the market that is foolproof and reliable. I hope you keep making these videos for everyone, as it helps so much, especially as there is no sales and marketing BS to con us out of our hard earned money. More power to you man.

[@AlloffroadAu]

Hi John, thanks for that the TJM locker is not new it’s the old McNamara locker the design is on the market for many many years

[@tomjones400]

Great information, presented in an easily understood way, with what I thought to be a very balanced approach. Appreciate your efforts in making this video. Now I'm armed with some very relevant knowledge, I know which diff locker I'll be going with. Glen

[@AlloffroadAu]

Glad it was helpful!

[@OffTheBeatenPathAus]

Great combination video with actual technical operational information. Agree the fact the TJM is not pressurised is a big plus, but till a friend pointed this out I had no idea about the elockers disengaging when rolling back.

[@AlloffroadAu]

thank you

[@Aliens_Gonna_Get_Ya]

Thanks Stefan...... We're in the process of putting front & rear lockers into our Wrangler JK..... So, that's good info....

[@johnostrum6953]

Literally every bit of information I was looking for. Superb video. Thanks so much

[@AlloffroadAu]

My pleasure 😊

[@phillipsampson4001]

Thank you for all the work you put into this video. Fantastic review. It was professional and insightful. Explaining the clear differences between all three lockers. You have made my decision as a not so full on enthusiast to keep it simple.

[@AlloffroadAu]

Glad it was helpful!

[@johnrogers5825]

Excellent video. This has me leaning toward the TJM. I have been researching for months and am still undecided as there isn't one locker that is perfect. I don't like that disengagement with elockers, and am wary about ARB O-rings in particular. This video has been the most honest and best explained one that I have come across so far. You appear to be very honest, and don't appear to be promoting any locker, even though you have gone TJM. Honesty works for me, and I disregard information given by others who I can 99% tell are promoting something for a company and what they can get out of it.

[@AlloffroadAu]

thanks, mate

[@Iandental]

My Gu Patrol it's ARB Airlockers fitted December 2001 , 21 years later there still going strong although the air compressor has been replaced 3 times... The Airlockers were factory fitted and have never missed a beat and the vehicles has played pretty hard over the years and 500.000 kms. I wouldn't worry about those "O" rings to much ! :)

[@AlloffroadAu]

was a different design then mate o rings indeed where no issue in old design.

[@Niko-iw1sr]

@@AlloffroadAu I just bought a ARB locker for my 94 4runner, should I worry about the o-rings on the new design? Do they go bad more often than the old design?

[@bogged2theeyeballs695]

Same in my LC105. 20 years and no problems with my ARB Airlockers F & R, or the compressor.

[@rudiwebel582]

Thanks your explanation helped me understand the differences between the lockers and i now know which locker is suitable for me, well done .

[@rockynrolling6206]

Was just about to Pull the trigger on a Rear E-locker for My Dmax but rememebered this Vid so thought I'd rewatch it again just to be sure, but after going through the comments, I might save up the further $600 for a TJM Pro Locker, seems it'll save me money in the long run, Love your video mate and thanks for putting it together

[@AlloffroadAu]

Thank you very much.... Glad it helped.

[@debrown4093]

Great video. I have ARB in the front and rear of a Jeep TJ. So far I have had no problems. I Like the TJM Pro Locker design, the air line and piston can be replaced in the trail. Anything that can be repaired on the trail is worth having. Thanks for your videos

[@tomtrish]

Mate thanks for that. I have the ARB Air Lockers in the front and rear of my 100 series Cruiser and I do love them. They've been in since 2006 and the only trouble I've had is after putting a 3" exhaust on the car, at full flex the exhaust would break the air fitting as it exits the diff. I have since redesigned that exit system and it's fine now. I have noticed over the years that the compressor kicks in more often than it used to, so I guess a service to replace some o-rings might be worth it. It doesn't fail though,, so I'm still happy with them

[@AlloffroadAu]

If they are well installed they usually seem to be good, if there was no TJM I would have also gone ARB but installed by ARB HQ with the 5 year warranty

[@Aids45]

After seeing this video I performed a check on the e-locker in the back of my Mitsubishi Triton. I jacked one wheel off the ground and engaged the locker. Turning the tailshaft backwards until the difflock engaged, I then marked 12 o'clock on the tyre. Then I turned the tailshaft forward until the difflock engaged in the other direction. The mark on the tyre was at about 2.30, not quite 90 degrees of rotation on the tyre. I checked it back and forth a couple of times to make sure of my results. So while it is true that the difflock dis-engages and has to re-engage with a direction change, I can live with the minimal amount of rotation it takes to do this. Have put over 50,000 km on my locker with no issues and it has never failed to operate, and was simple enough for me to install myself on the driveway at home.

[@AlloffroadAu]

yes in most instances the disengage wont be noticed, what tyre size? Keep in mind the bigger the tyre the more it will affect you when lining up for rock climbs

[@Aids45]

Just 32's which are fine for my local tracks at Jellore. I have a front Lokka though which is always there providing drive to the front wheels.

[@darrindouglas1]

Excellent review. I have a factory rear locker in my NP300. As an "e-locker" it works fine (so far). I was thinking an air for the front, but I am convinced now thanks to your video. I have an on-board tank and twin compressors, so air supply will be a breeze. Really enjoying your videos. Keep up the great work....

[@AlloffroadAu]

Thank you Darrin glad it helped

[@ricardostravels3265]

Nice comparison, although it would be helpful "for newbies" to see the purchase price differences as well as installation cost differences. I agree - if you have the budget, TJM is the way to go.

[@AlloffroadAu]

yes prices do vary though quite a bit and change with time. Elocker is usually cheapest as install is quick and hence often promoted by workshops quick in and out money

[@donpardo1]

Hi Stephan, good choice. I had tjm prolockers installed 7 years ago on my 105 landcruiser still work ok, little air leak somewhere, but still do their job. I did choose Tjm above Arb, also because Arb would not give me warranty with their lockers, because I run 35 inch tyres on my cruiser and Tjm did. Maybe Arb do now, I have not checked.

[@neardood1]

ARB redesigned their air lockers. The older ones had o-rings that would wear out when the diff was unlocked and being driven on the road, resulting in blown out axle end seals, oil being pushed out by the air pressure when activated, ect. Definitely something to consider if purchasing a second hand one

[@AlloffroadAu]

Not that I know off, a friend of mine just had new set installed by ARB in December 2018 and they were leaking oil out the breather in January

[@superwag634]

I’ve had my ARB lockers front and rear since 2003 in an 80 landcruiser diesel manual. Both lockers leak oil out the pneumatic solenoid upon disengagement. It’s like a puff of oil vapour and my firewall is covered in diff oil. Ive had three diff rebuilds in the rear, often after rock crawling. The lockers used to shear bolt heads which then floated around the diff centre until they smashed into the crown wheel and pinion and that was always a horrible sound and experience. Then I got it modified with more bolts. The o rings are always worn and the elastomer loses elasticity over time.. It’s just not a durable design in my opinion and I’m a mechanical engineer for almost 20 years. Just waiting for the upcoming fourth diff rebuild 😬

[@paulrushtonhorsemanship5445]

I had an ARB lock for over 23 years only problem was the air compressor died after 22 years so couldn’t complain got my moneys worth. Locker never failed and it got smashed all across the top end. 👍

[@AlloffroadAu]

yep the old ARB's where even better unfortunately ARB changed the design at some stage

[@SeriousSchitt]

Great video fella, thanks. I knew from the onset there were differences. When I got my lockers, in my 2003 Hilux SR5, four years ago, I don't think I'd heard of the TJM locker, I was sold solely on the ARB. My mate told me about the 'E' locker, and having never gelled with the notion of a cable (such as the OX locker) I did most of my research around the ARB and the Eaton 'E'. As mentioned my preference was with the ARB, and it takes a lot for me to change my mind once I get set on something, however, once I found out that they required a seal inside the diff, and reading someone's write-up stating that they were a mechanic dealing with a lot of the ARBs, and saying "who would want to fill their diffs with compressed air? I mean 'seriously'"? I started to focus on the 'E' lockers. The notion, like you mentioned, that these things undid between forwards and reverse, really didn't sit well with me at all, and psychologically still don't, however, that's what I ended up going for (front and rear, very simple operation installed by myself a 'meat worker') and have not had a single problem with them. I'm 'only' a hunter, requiring four wheel drive to get me safely back up the odd track that I encounter, however, I've never noticed them unlock whilst I've been out there doing it. Perhaps I'd change my mind if I got into more serious 'technical' wheeling, I don't know, but I'm certainly not about to rip them out, for me, they're perfect. Thanks.

[@JAMESWUERTELE]

The Ox uses a cable, air, or electric. The cable is a push cable not a pull. I’ve had 7 years and over 80,000 miles of trouble free problems in my D60

[@ThePaulv12]

You seem to have closely analysed the merits of each diff lock. I tend to agree with you and your choice - however - this internal air line fracturing business is IMO due to the flexing of the diff housing. I have had experience with ARB diff locks and this has happened in a number of occasions over the years. It doeth shittith me to tears since when you need it most it fails! This is why i found you as i was wondering about electric activation as a means of negating this frankly unnaceptable internal airline BS. I now find the e Locker has a severe limitation. Look all we really need is an electric or cable dog clutch to stay in foward and reverse on a decent 4 pinion carrier. I ask why does it need to be this hard?

[@lukemorgan8551]

Awesome video mate I was debating on the TJM or the Harrop locker but now this has helped make up my mind

[@AlloffroadAu]

Not sure which Locker to buy? ARB, TJM or Harrop E-Locker? I just replaced my five-month-old Harrop Eaton E Locker as I found out not all lockers are the same... Unfortunately, there is a lot of misinformation out about the different locker types so after now having used all three locker types and doing quite a bit of research I thought I share my findings in a Video which may help someone purchasing the correct locker for his application. Please don't forget to share your Locker experience in the comments!

[@mimixownzall]

Ox locker greater than all of them

[@AlloffroadAu]

yes I heard that they are very good and could be installed as e-locker, air locker or mechanical locker not very common here though

[@wyattscott3526]

I don't think so. Seen two of them fail quite quickly in light weight vehicles. I've used ARB Air lockers now exclusively in our builds with zero failures.

[@stuartjohns2779]

AllOffroad 4x4 Adventures TV I got Jeff McNamara to make my diff locks around 10 years ago for my 80 series just before he sold the design to TJM. They have been through hell and back and still work perfectly. The air ram actuated locking ring was why i went for them aswell.

[@AlloffroadAu]

I reckon that will last you another 20 years, still handmade in Australia at the time, awesome

[@michaelclement2124]

Very good detailed Information. I don‘t have the posibility to do what you do and i never will, but i love all the details. Thanks for making al that stuff.

[@tengallonz]

Great video Stefan, I didn't know this about the eLockers, it wouldn't really be much of a problem for me with how and where I drive, but I can see how it would be a critical problem for the tech stuff you do. Also great to see a factual video presenting real information rather just more heresay that forums etc get flooded with. Great stuff!

[@AlloffroadAu]

Thanks a lot mate, I tough the video may save someone the 4K I spend on elockers

[@larryjanson4011]

this is why one must have a Detroit locker in the rear. and never use the clutch while climbing. as you never "lose" the lock, and should never "roll: back. slide yes... but that is traction a different thing.

[@bearfarmer]

Not happy with my e locker at all. Northwest hill climbing were you have to back up and try again, the lock unlock mannerisms are a pain. Will switch to ox

[@craigquann]

Well for the weekend warrior/occasional off roading, the e-locker would be the way to go. But for the more dedicated people. Air lockers plus an air system that can also inflate your tires should be the setup you would want.

[@ewanmcleod6487]

Thanks for the time and effort you put into this comparison and video. It helped me make my choice of a necessity.

[@AlloffroadAu]

Thank you comments like this are appreciated

[@simonmul449]

Thanks for that insight into lockers. Very helpful in choosing which is most suitable.

[@dirtyoff-roadaustralian5525]

Great one thank you for clearing that up now it’s a lot more understandable between the makes 👍🏻

[@vdj79r4]

Good explanation, I have e-lockers in my Landcruiser and am happy with them, despite having one explode and destroy my diff!-was repaired under warranty but did have to drive 100 kms in front wheel drive! Only other problem has been with a poor quality fuse holder which caused locker not to work due to no power. If I was to buy again though I would consider the pro locker for the same reasons you mention.

[@AlloffroadAu]

we have two people in our club who recently found a sheered of small bolt on the magnet in the diff looks like a grub screw, must come from E-Locker will see how Harrop handles the warranty...

[@vdj79r4]

AllOffroad 4x4 Adventures TV yes the spider gear shaft is held in place with three small cap screws, they fell out in mine allowing the shaft to come free and reek havoc! Eaton said it was due to a bad batch of thread locker?! Locker and all damaged parts replaced under warranty

[@littlefarmer32]

I have used the Detroit locker in the FORD 9 inch , on my 85 full-size BRONCO. Best dif lock on the planet

[@AlloffroadAu]

More of a unlocker but heard they work quite well

[@stevenwalker984]

Do you find it a bit clunky. I used to run a lokka in the rear of my old hilux and whilst it worked well it was very noisy and clunky when turning. I presume they are a similar design.

[@sha6mm]

What I would like to know about air locker is can moisture freeze in the line in below freezing temps. Like in North Central USA where temps can go to -30 F .

[@simonjones388]

thankds for the technical breakdown I am looking for a pair of lockers to go on either my patrol or my Isuzu trooper neither 4x4 is new they are both used as tractors to pull broken down vehicles back to the public road where they can then be put on the recovery truck and brought back to the garage I have previous experience of mechanical limited slip diffs but in the muddier fields the 2 4x4s could do with a little help( so locking diffs to the rescue )

[@Doodlkine1]

An excellent explanation. I was looking to get either an ARB Air Locker or TJM Pro Locker in my new LC 200 series. I will now have the TJM Pro Locker installed.

[@AlloffroadAu]

Good choice! They have not let me down so far

[@ausguy4385]

Have a 200 also. How did it go?

[@ooaqici82qb4ip]

First of all that’s a good informative video.I had arb lockers installed on my new hilux and I’m now on my 4th set of lockers after travelling only 87,000kms. The last failure absolutely destroyed my rear diff and housing when a crown wheel bolt FELL OUT!!!! As they don’t use locking tabs but recommend lock tite.to keep it together. With a bit of luck the car should be back on the road this Friday and come Monday I’m going the Tjm to get the pro lockers fitted. I no longer feel that my car is reliable and I can’t take it anywhere I can’t get a tow truck and after researching all the lockers I’m hard pressed finding negative feedback about the tjm’s. This video helped me make up my mind. Thanks again

[@ooaqici82qb4ip]

Ps the new arb lockers will only travel around 50kms from the ARB workshop to the TJM workshop where they’ll be cheerfully ripped out n replaced. Anyone want to buy some cheap arb lockers for a 2013 hilux SR5, they’ve only done 50kms $750 for both front n rear

[@benjaminprince6424]

4 lockers, under 100k, holy shit, should not even have gone past one set!

[@fuzzynuts54]

Your bolt falling out has nothing to do with the locker. That is purely installer fault. You can most certainly use locking tabs on the arb. No matter what brand you choose, if you don't run locking tabs, locktite on clean oil free threads, you run the risk of bolts falling out.

[@AlloffroadAu]

Interestingly we had this happen to all 5 people in our club with e-lockers, one vehicle needed the whole axle housing and centre replaced twice within 12 month, the second vehicle twice within 2 years installed by Harrop so doubt this is just an installation issue. My theory is that they come loose with heavy use as all of us use the lockers on a weekly base.

[@brbadventurer]

11:36 When the air line broke in your diff did it blow gear oil out of your seals?

[@charliebaker4259]

Thanks for the comparo. Informative and non biased.

[@AlloffroadAu]

Thank you very much....

[@beerturbogarage]

i was looking forward to putting an E locker in my next 4wd, but after learning this i think ill avoid it. iT does make you think, the TJM could be actuatated with an electric solaniod instead of air also?

[@the.magnus]

I love your accent and the way u talk lol. TJM is your recommendation for reliability and toughness for expedition? Your expert opinion is of great value

[@AlloffroadAu]

yes TJM Pro Locker seems to be the best option...

Don’t know how to thank you for sharing this deep knowledge . I never knew these facts. I appreciate that 🙋‍♂️

[@StormbornJKU]

I just installed an Eaton e locker in the rear and noticed how it disengages and reengages. I like to do some pretty hardcore wheeling and that may prove to be a con for me. I suppose I’ll have to wait and see to find out. As long as constant momentum is kept it should be fine. Lockers allow you to spin tires when stuck, so just keep momentum is my fix. We’ll see

[@EmpTy-kf2rq]

Great info. I also watched Filthy Motorsports video before making the tough decision. I went with Harrops as I didn’t want to add additional failure points - air compressor, air lines and O-Rings. TJM lockers are not available in USA. Also, I am not usually rock crawling like in your video when off-roading and I do have an automatic transmission and left foot brake to prevent roll backs, most of the time.

[@ananamusly]

TJM is available in USA. Search for them on JustDifferentials.com

[@westie4ageturbo.749]

Thank god i watched this. And thanks guys!! Im going to put lockers in my D40 as the limited slip is well and truely stuffed.

[@markhoffmann2771]

Haha. Great vid. Thankyou. I have e lockers. They get a good work out for sure. As you say all good in the area you play in. A mate of mine John said it in great words on the track one day as I had an issue with e locker but didn’t know it haha , the thing is you can hear an airline that is pinched and know there is an issue , as with a broken wire you don’t know till it’s to late. Keep up the good work. Steady steady mate.

[@AlloffroadAu]

thanks mate

[@dartmoordave]

I have the stock LSD on the rear of my LWB Trooper and an Aussie Locker in the front. As it has 2/4 option the front doesn't affect handling but care is taken when in 4. Works great for me in the UK. I could buy a used trooper for the price of an ARB so, no argument. NO WIRES, NO TUBES, NO FAILING. As long as you remember not to abuse the half shafts.

[@hardliquor4x493]

Another quality video stepan i thought of an e locker for my front diff before but since one of our fellow drivers in his disco had one installed and failed twice i have stuck to my auto lokka in the front only no air lines or switches and has been bloody awesome the only thing wrong with them they cant be switched of but they are a bit savage when first installed i would not put an auto lokka in the rear btw

[@AlloffroadAu]

I used to have an Ashcroft ATB in the Disco 2, liked it for 99% of applications but still was reactive so stuffed up a few rock climbs hence I changed to an Air Locker at the time

[@hobiechhina]

Me "Mate, A locker is a locker period!" Me now - Boy was I wrong :/ Thank you for such an insightful review!

[@AlloffroadAu]

Thanks mate have to admit I thought the same until I started looking in to them closer.

[@MattBlack6]

Great video thanks. I've also watched the full filthy motorsport video. I'm far from an experienced off roader of my 80 series but to me it looks like TJM is the way to go. Having a compressor onboard is vital for tyres anyway, so I'll have it to do both. Cheers.

[@JeepTJWheelin]

Excellent and well explained video. I have an '05 Jeep TJ Rocky Mtn, and I'm looking to do more challenging off roading, will be getting either the TJM or ARB lockers with 32" BFG MT's.

thanks , so much for the great info, your advice is always very good and i think tjm is my choice also ive herd so many bad things about ARB lockers

[@differentials]

The TJM Pro locker Is my dad's diff lock. Dad invented it 40 years ago. It used to be called the McNamara locker, he sold the design to TJM. just before he sold the design to TJM he rang up ARB and told them, "would they like to buy the design and call it the ARB locker 2 so they have no competition because TJM wants to buy it". But ARB said nahh not really. I bet they wish they bought the paintent off him now hahahha

[@AlloffroadAu]

Lol they should have bought it pity TJM does not do much with its locker.

[@differentials]

@@AlloffroadAu TJM makes the pro locker all wrong. The pneumatic cylinder throws further than the locking ring and there is a few other mistakes they do when they're manufacture this Pro locker. we have told them over and over and over for the past 10 years what they're doing wrong and they keep making them wrong

[@differentials]

all these large companies that make all this aftermarket stuff just don't care all they do is make this crap as quick as possible and try and get as much profit you tell them what would make it better what they're doing to make it wrong all this all that nobody ever listens. Corporations are disgusting

[@differentials]

Every single time we fit a TJM Pro locker to a customer's diff we have to start modifying a brand new diff lock because they're made in correctly.the normal person wouldn't even pick up that they're made wrong. And would just fit them as they are. And then while in operation/diff locked it all jams up and where's out

[@gvansomeren]

@@differentials Can i get some TJM "fixed by McNamara" lockers from you? As I have finally got the wife onboard with forking out for lockers and this is my one chance to get them and I want it done right. In Tas btw so a fix and ship kind of thing.

[@sq33g33]

Love your videos. Also about to pull the trigger on a TJM Pro (air) Locker for my 60 which I had decided a few years ago was the best option (but didn't have the funds), only to find out now you can't get them anymore. I called a few dealers and they didn't even seem to know themselves, so must be recent. I also heard parts issue but that doesn't make sense. Might have to go ARB but I really don't like the o-ring leaks you year so much about. This video just makes me want the TJM pro even more. Surely there is some stock lying around somewhere???

[@AlloffroadAu]

just get ARB installed and warranted by a good diff place and you should have no prong issues

[@cookie13spike]

Great info! My factory locker in mitsubishi challenger has started playing up so looking at drop-in options I found only harrop do a suitable one. Interesting your findings with the elocker and something I need to seriously consider as do alot of technical driving! cheers

[@lukeagex]

Straightforward and transparent review, thanks. Very helpful for when/if I get a locker for my Prado.

[@AlloffroadAu]

Glad it was helpful!

[@6402457]

Damn I was all about the Harrop E-lockers, but now watching this knowing it might not work if u roll back is a no go for me. Cause I get myself into sketchy situations pretty often and I need my lockers to work when I need them to. Definitely getting an air locker now most likely Tjm... thanks for the insight.

[@bignedau]

Learnt something about the TJM, great in site, my question is, Is the TJM as indestructible as the ARB lockers.? I thought I was decided, now I have more questions. Cheers

[@AlloffroadAu]

Haven’t had a issue with it on paper should be stronger then ARB

[@dontask8979]

Keep the vent on the diff itself clear, and clean lube and the O-rings will last many years. You MUST clean out all the air passages several times. I have seen crap in the passages and the 1st time you engage them, its fine, but when you disengage it, it spits the crap out and in between the o-rings. They do a nice job keeping them clean, but the surface is ground, and you have a good chance of getting some crap out of it. I ALWAYS get crap out of the copper tube. All that will end up in the o-rings. Surgical clean and you are good to go.

[@melshingleton5991]

Love my ARB lockers. However, it's very important that the air hose is installed correctly and away from heat. Last winter, while wheeling in 5' deep snow my front locker failed duento melted air supply line. The company who installed my lockers ran the supply line too close to the exhaust and it melted. It was also out of reach and so I had no lockers.

[@ninjadragonblade]

my 79 cruiser came out standard with a Toyota factory locker...hasn't missed a beat since iv used it. in saying that the rear diff lock took awhile to engage because it was new but its pretty good now, my only bad remark about it is it wont engage without 4wd (H4 or L4) and its either: rear lock or front AND rear. I know 9/10 times if you want the front the rear should be engaged anyway but I like having full choice over a vehicles abilities. if I could pick or choose at the end of the day id still pick ARB Airlockers

[@AlloffroadAu]

Toyota Factory Elocker is a very different design to Harrop Eaton does not have the issue Harrop has.

[@jackcraigaptos]

even though lockers are just a bit down the road for me, this is exactly the info i'd like to get started. my '01 F150 has 422K+ miles on its oem IFS. adding a locker suggests i upgrade the ifs at the same time for robustness. as we all know, you aussies know best how to get the most from your offroading hardware, what kind of ifs do you suggest for an aging truck destined to do more offroad as she gets older?? Thx!!!

[@JAMESWUERTELE]

I have OX lockers in my 97 F-350 7.3. Flawless operation for years!!!

[@djmaunder]

...bit of a shame that the Aussie made Maxi-Drive locker also wasn't included (vacuum operated); granted that they are only made for the Landrover / Rangie scene, I guess it is fairly limited.

[@AlloffroadAu]

Hi Have MaxiDrive lockers in Tiny and also had them in my 110. Best lockers in my opinion but not included as they are not made anymore for years so no way to purchase unless you buy a used one.

[@jakeweg4886]

This is making me like my 3rd gen 4runner style locker a lot more

[@donaldmccain4084]

Thank you Sir, I am currently researching lockers and this vid really answered many of my questions, I appreciate it, thank you!

[@AlloffroadAu]

Glad it was helpful!

[@c130aviator]

Added your video to my arb install playlist. I chose arbs and installed my own gears. Thank you for helping me explain my decision.

[@AlloffroadAu]

Glad I could help

[@Marco-fi6gv]

Thanks for the review! Filthy Motorsports is awesome too, love that channel.

[@ZikoMario]

Hello, I have a question, can you mount an e-locker to normal street car and drift with it, in locked mode? I am extremely curious and I didn't find a single video on the internet with someone using it like that, everyone just weld an open diff to drift.

[@wasneva]

You sure can mate, you can get them for some ford ute diffs and most toyota diffs.

[@4x4patroladventures4]

Very good information! I put a TJM Pro locker in the Patrol rear. VERY happy with it!!

[@AlloffroadAu]

Right on

[@Roaming-Mike]

What’s he best locker for the front diff?

[@stevengreen9738]

Like many I thought these three would be similar in performance, I am going to put a front locker in my BT-50 and am now looking to TJM, can you advise me on whether there would be any improvement replacing the rear OEM locker with a TJM also? thanks for a very informative video...

[@AlloffroadAu]

Only problem with TJM is that they don’t cover many vehicles and brands. I’m not familiar with the BT50 factory locker but if it works would not see a need to replace it.

[@travancorepistons7309]

I have a 2.8 diesel Pajero 7 seater in India.. here Mitsubishi didn't gave us rear diff lock option. I wish to have a rear diff lock.. please suggest a good one.. and it cost...

[@AlloffroadAu]

sorry no experience with Mitsubishi but I assume you can get an ARB air Locker for it

[@jasonmyer3615]

For ARB airlocker, You gotta import one. I don’t think they have an outlet in your country.

[@scottwilson5089]

Great video! Did you do a front diff upgrade at all? I have read about the problems the have in reverse. Is there some upgrade you can do to strengthen the diff?

[@AlloffroadAu]

solid pinion spacer

[@devinjordan5140]

So if you have an e-locker. You should use your left foot to hold the brake while you roll on the throttle. This way you don't slip back. An additional step, but may be a helpful trick even with an air locker. I do it even in 4lo without my locker engaged and it seems to help heaps with gaining tracking because you aren't fighting the rearward momentum before gaining traction to move forward over an obstacle.

[@AlloffroadAu]

The issue is more if you need to wriggle yourself in a better spot in tight conditions no foot on the break helps there. But when driving Technical we often drive double footed right accelerator and left brake.

[@devinjordan5140]

Ah yes, in this situation you might be out of luck with the elocker. I have the Tacoma TRD Offroad with the OEM elocker in it. Haven't had this issue when stopping right before popping the rear up a little ledge, but I don't wheel as hard as you do. I'm sure I would notice the issue if I hit what you hit.

[@Michael_Mears]

Stefan, great video. I'm limited for options, either Harrop e-locker or ARB air locker, because the vehicle is a 2018 Holden Colorado (stop rolling your eyes). They don't make a TJM or Lokka for this ute. Having considered your views, I think ARB might be the better option for me...

[@AlloffroadAu]

Didn’t roll my eyes mate everyone has different requirement if the Colorado works for you it’s all good. I agree would also go ARB (did actually in the Jeep) get it installed by a diff place who still offers the 5 years warranty if you in Sydney see Jmac

[@lsvej1]

Thank you for this video! I been searching on a locker and came across the tjm pro locker not long ago an read up good things about there design and quality and this video has helped me made my decision on which locker to go with in the future. Seems like allot of technical off roaders choose tjm over Arb

[@AlloffroadAu]

Glad I could help!

[@TrueDaturaMindNz]

hi there can you let me know were you get those front lights for the 100 series they look sweet

[@adrianw3985]

Good information, I wish the Grizzly or Detroit Locker was available for my Toyota 8.2 Diff. I have a Grizzly Locker in my Nissan and it has been flawless for over 30k miles now. Probably going to go Harrop for my Toyota 8.2 despite its minor disadvantages.

[@markdavies675]

How are your lockers going so far ? , any issues , lam thinking of going the tjm path also but rear only as that’s all they do for the 200 series ..cheers Mark.

[@AlloffroadAu]

Lockers go well no issues whatsoever and they have been used a bit

[@PatrickRich]

Its interesting that the eaton uses a ball ramp design but I guess thats what you have to do to apply large reliable force with a small current. I've got the Toyota e-lockers in my 80 series and I think its the best way to do it as you don't have to deal with air but it is a locking collar design. but I realize that if your axle wasn't designed to accommodate a shift fork and actuator its no good.

[@AlloffroadAu]

Eaton uses 3 different designs the ball ramp, pin ramp and the new Elocker4 which does not have the shortcomings but it is only available for a Dana 60/70

[@rockcrawlerchurch2976]

I have nicks old rubicon diffs in mine with the front being the factory locker and the rear being a 35 spline arb unit. I have had oil being pushed out through the breather. Its something im going to be keeping an eye on. Before having these installed about 2 months ago, i was running a harrop elocker in the rear and just the jeep traction control on the front. I have noticed a difference with the car being twin locked, and have to also say the change in ratios was a bigger improvement again. Being in a manual i would have to say the rollback problem with the e locker was a pain. As each trip goes by im finding more and more confidence. What is nick doing to your land cruiser at the moment? I saw it there the other day when i went to pick up some parts.

[@AlloffroadAu]

Thanks for sharing, few little upgrades to Cruiser HD Torque Converter, 300M axles, splined flanges etc...

[@RedesCat]

elockers do work differently in australia vs america, they work upside down

[@AlloffroadAu]

lol that's good one

[@DylanYouSonOfABidgeNelson]

It's called reverse rotation or high pinion. The southern hemisphere is reverse cut and rotates opposite of the northern hemisphere to make sure the earth doesn't spin off keep course and keep traction while rotating around the sun.

[@ottoswinebar]

Just discovered your channel via this video. Keep up the great work.

[@AlloffroadAu]

thanks for joining in

[@damingallo1]

Hello! what do you think about the AUBURN GEAR ECTED locker or now called the Select-A-Loc™? I am thinking in this because offers the locking option (not sure if it is 100%). I am between this an a tru-lock from eaton.
