Any expert and experienced operator will tell you to put a single locker in the rear. This is because all the torsional forces of braking, turning and impact is in the front of the vehicle and a front diff is under enormous pressure and stress before you lock it together and bind it tight. 1) I snapped my front CV in my IFS 100 series when I wasn't even 4wdriving. All I was doing was a 3 point turn on a moderate side slope and I accidently engaged the front locker whilst the front left wheel was off the ground 5cm and spinning freely and BANG. That's how tender your front diff is. 2) One rear locker makes 4wdriving 10 times better but a 2nd locker just makes it a little better. The best place is in the rear. 3) For going down slippery slopes it's best to use a single rear locker switched on and an open front end for steering control. 4) It's best to use your front locker AFTER passing the front wheels over an obstacle so that you don't smash your front end. Look after your vehicle. 5) ARB, along with Army and military vehicles and traktors all make you engage the rear locker first. I wonder why ? They're not stupid. 6) Lockers can get you into more trouble. Lockers make you slide sideways faster and easier than if you have open diffs. 7) Front locker = frugal use. Careful use. Little use. Your vehicle was made to flex and lockers stop that from happening. Lockers can mean breakage. Been there, done that. All my 4wd's have twin Tony Roberts differential locks. Hope this helps someone Ronny. Skål

[@lucasspiros]

Ade Larsen i agree your comment 👍

[@rebeccaedwards3784]

Ade Larsen I thought all vehicles like this made you lock the centre diff first before locking the rear? Not the rear first? ? That's how it is on the first gen Quattro system. First you lock the centre then it lets you lock the rear.

[@678friedbed]

an experienced driver would know when to lock and unlock to avoid failure.

[@MudratsHuntingAnOutdoors]

100 series is your problem there mate the front ends in them are weak as piss I have in the previous Gq Patrol run 37” tires with just a front locker with a tight lsd in the rear through 10 years of constant abuse through 4wheeling every weekend an doing comps under extreme conditions only ever broke 2 cv’s I had front an rear lockers an found the rear only to be useful on downhill descents an straight uphill climbs as soon as it’s an off camber climb with deep ruts a rear locker is useless it just adds to much torque to the rear end making the front end want to dangerously lift to the point of roll over front locker will give you the added torque to the front to pull the nose down all I run in my touring rig these days is a front an there is nothing it cannot make look easy

[@victorsinclair3707]

So is this Tony roberts locker better than tjm pro I've been hearing about? How is it actuated?

Thanks again Ronny I not too long now just purchased my first Nissan (GU Patrol), a switch from Toyota, and most of my trucks have all had both front and rear lockers, but this time around, I can only afford to get one fitted until later in the year, and after much research and deliberation, I rewatched this vid once again, and have decided to go with the rear over the front, as I always find your down to earth experience, truth, and explanation very insightful and educational! Thanks again Ronny, safe travelling, and I hope to catch you out there one day. Cheers, Joel.

I haven't watched his new videos for month. Just too much "You NEED to watch this, this is how it's done, don't listen to the others they are all wrong, I alone bring the salvation, where is my church" bla bla.

[@rich7447]

Great video. I drive a 3/4 ton pickup (no-IFS, live axle) and the biggest issue with stock pickups is that there is very little weight above the drive wheels in 2wd and the front differential is always an open carrier (unless you buy a Ram Power Wagon). I switched out my rear LSD for an ARB switchable locker and it helped in some conditions, but when the snow got deep I got stuck unless I had an extra 1,000 lbs in the bed of the truck. I finally installed the AAM selectable locker out of the power wagon in the front axle and am able to keep moving when everyone else is buried by the snow.

[@DPCB01]

Great video Ronny! Just got into 4WD and your videos help a lot!

[@cfltitan]

Hello from the USA! I love watching your videos. You made great, valid points for your style rigs and terrain. You're more an overlander on soft sandy/muddy terrain. I'm a rock crawler in the northeast of the US with a Jeep wrangler (solid axles front and rear). To us a front locker is much more important because it'll pull you up over big rocks and ledges whereas a rear locker does no good just trying to push from the rear. Granted, 99% of us have front and rear lockers but if we could only choose one it would definitely be the front. Like I said though, two totally different types of wheeling and two totally different types of rigs. Keep up the excellent videos! And go have a vegamite sandwich! Lol

[@arielgs]

I totaly agree with you. I also had lots of driving in my old Cherokee XJ in soft terrains, and in that case rear locker works perfect, but now I live on rocky mountains and have a JK Wrangler. No locker now, but will go with a front auto locker soon!

[@eranwilliams4098]

That's a great point. His comment is supreme in "overlanding" but for a crawler your point is supreme. Incredible context for why someone would argue against his point. Their rig would also look totally different than his! Great context. Thank you!

[@NICUofficial]

super interesting, as a North American "overlander" myself but who also has interest in rock crawling (especially to get to the coolest campsites, hikes, etc) I do dream of adding a front locker to my 4Runner. But it's a long way off and I've never found the limits of my current rear-locked setup anyway... just in the intermediate stages of learning all this 4x4 stuff. love comments like yours, they really really help me learn

[@garviere]

Thanks for that, I was contemplating exactly this question and I had actually, through ignorance or inexperience, come to my own conclusion that a front locker would be better as you can still steer where as a rear locker will push you in a straight line and over power the steering. So it was good to hear from you that the opposite is true. One of those occasions when theory is proved wrong in practice. Nice one, thanks.

[@MaherTrex500]

Totally agree. The best setup is rear diff lock with front LSD torssen differential Very few trucks comes with LSD front differential. But if your truck has one u will never need front locker.

[@josephkool8411]

I think that's how Raptors are setup

[@JasonISF]

Torsens are great, got one standard in the rear of my Subaru 👍

[@MsandMrspinact]

I've been binge watching your videos for a while now, and although these older vids aren't as polished as your newer ones, they bloody good for a newbie like me.

[@iextreme4wd686]

I prefer a front locker myself, but your reasoning if you could only do one is sound. Great channel, keep the vids coming.

[@TucsonDude]

I agree, Ronny. I owned a Jeep Rubicon in Colorado. On semi tough trails, I occasionally used my rear locker. I bet I didn't use my front locker more than a dozen times unless bogged down in deep snow, mud or on a steep ascent.

[@maxpower9175]

The car I've ordered comes with only rear locker, and thanks to your video I realised that will be enough for me. Thank you.

[@seancraig7488]

Only just found your channel and loving it! My daily driver is a W460 G Wagen that has factory front and rear lockers, and have to 100 percent agree with you that a rear locker is far better than front.

[@stocky9803]

I run an auto locker in my GU which works awesome. I have also have a very tight LSD which drives the wheels on full flex so personally I wouldn't choose a rear locker but obviously depending on the vehicle it changes. The way I look at it is especially in IFS your always lifting wheels off the ground, if one wheel is in there and its spinning it only leaves the rear wheels to drive which in alot of cases isn't enough to progress your vehicle forward. If you have a nice LSD you can still have drive to both of your rear wheels (Most vehicles arent ideal) and one contacting wheel on the front that also has drive giving you 3 wheel drive worst case 2wd which is equivelant to having just a rear locker. Moral of the story is with a front locker you still have 4 potential wheels that can drive, with a rear locker you still only have 2wd

[@Malc664]

Hey mate. After 3 years with your auto locker how is the reliability? Spartan or Lokka or Eaton?

Hello my name is Nuno from Portugal , i have a suzuki jimny 1.3 and i saw your video. i agree with you i think that you are right. I love you video i hope i can see more. videos with 4x4 tecniques. GO ON :D

[@The_Aussie_Enquirer]

Hey Ronnie, first off mate I just want to say I love your videos and your obvious passion for what you do 👍.. in regards to the locker debate though I have a different perspective as a patrol owner. It was mentioned by someone earlier that your current and previous rigs were leaf sprung as apposed to coils. I think this has a big bearing to play on the debate as Patrols have waaaaaay more wheel travel than most other rigs out there. My experience has been that a front locker on a patrol would be a better option than a rear if only one could be had. I drove for years with a double locked GQ ( arb air lockers that were isolated back and rear I.e I didnt need the rear one in before engaging the front) . My reasons for saying the front is better on a patrol are this 1. The patrol has sooo much travel on the rear that it is rare that a back wheel is off the ground. It is nearly always the front wheel which lifts due to more limited travel on the front especially when climbing hard hills.2. Yes , double locked vehicles are harder to steer than just a rear locker but that’s often because an engaged rear locker will keep pushing you like you are on railway tracks. If it’s just the front locker on it just drags you where you point it. (There has been a few times that this ability has gotten me out of serious trouble). 3 I have been out on trips where I have purposely left my rear locker off and only used the front one as an experiment and left all my rear only locked friends for dead in the rough stuff.This was not to be a smart ass but just to compare the differences and learn about what we could do. I think I heard you say that your lockers are in series ? I.e you can’t put your front locker on unless the back is already engaged? I reckon you should try and get them isolated so you can only turn the front on and see what you think ? Keep up the good work mate !!

[@Justforfun-ek7et]

Makes my decision easier, I will get a rear locker for my Tundra. Thanks brother!

[@bignedau]

If only one locker to get, no question it has to be the rear. Great vids

[@JoeOBremski]

Good thoughts... Depends on the terrain though. I'm 95% rock crawling and when climbing a ledge where you need to approach at an angle front locker is king. This is that same sort of scenario you encounter in rock gardens where you are climbing over single large rocks one at a time (30-40" tall boulders, etc.). Soon as the front end unloads you're not going anywhere. Now on dirt roads and such I do prefer just the rear because it does make it much easier to turn. Usually the front end is weaker parts then rear as well so you want to let the power "slip out" vs bind and bite stressing front end parts... Rear locker is also more fun when you come into a corner at speed because it helps break the rear end loose if you want to slide it around the corner ;) So just depends on where you wheel most but if you only have a few hundred bucks to spend on an upgrade your first purchase should be a winch! Front locker or rear locker WILL leave you stuck at some point but the winch will always get you out! Plus it gives you more opportunities for bragging rights when you pull your buddy out, ha!

[@Ronny_Dahl]

Joe O'Bremski hahaha I like your thinking about the winch,...

[@grantlandneil]

+Joe O'Bremski Last night I experienced what you were talking about. I came up to a big rock face. There was nowhere else to go. I had to go over it. Front diff locked in and I was up and over. I did have a friend of mine hook a tow trap to my front end and tie to a tree, just for safety. I am on a Honda Rubicon atv and have no winch yet. I have not made up my mind yet, but I think I am going to buy a Superwinch Terra 35. Also have not decided on steel cable or synthetic rope. Any advice?

[@JoeOBremski]

grantlandneil​ I prefer steel because you can drag it of whatever and it won't break. Rope can get cut of jagged rocks. The synthetic tends to "meld" into a mess on the winch if it's not rewound nice and tight. The rope can get sucked into a loose spool. Now steel does have draw backs. If it breaks look out, rope is safer but treat steel properly and you will be safe! Stay out of the way when pulling. Also those sharp burrs suck. Gloves need to be used always. Steel is cheaper too but heavier.

[@grantlandneil]

Great points! Thanks!

[@grndragon2443]

+Joe O'Bremski wouldn't this more depend on your transfer case? some lock both front and rear together, while there are ones that have 40/60 ( f/r) split of power and so on.

[@pwatom22]

My only comment is you have covered this perfectly.

[@stanwardoshiro]

Agreed. All 3 of my 4x4s have front and rear lockers but the rear lockers are always the one to be used most often.

[@stephenbartlett4992]

In regard to my 1996 80 series FZJ80, the rear axle rating is greater than the front axle rating according to specification data. Also, when purchasing the factory Dash Locker Switch, it actuates the rear locker before you can activate the front locker. As such, all seems to point to rear locker first (strength) and front locker second (extra help)

[@trinityfoxxx]

Great advice and yes I got a quote for $1600 for just one locker and I'll make it a rear one now :)

[@greenhound87]

I have both. But I put in a front locker first as the rear had not been released at the time. I found the front locker made a much bigger difference in capability compared to the rear. Probably because I have IFS with limited flex up front, and I had a pretty good LSD with decent flex in the rear to help out. I also installed it myself to save costs so that wasn't an issue. So, if you're talking about a solid axle truck (like your 79 series), then I would think a rear would probably be better. But with IFS I've found the front to be a much better investment for me. What do you think Ronny?..

[@danielsouders5553]

I really appreciate your video; I'm very new to offroad and I purchased a 2000 4.0L Ranger with the Dana 35 front and Ford 8.8" rear; I've been looking at front lockers due to budget and use; and again I'm very glad to have found your video. Great information man, you potentially saved my a bunch of wasted money

[@fjron]

I am running a lunch box locker in the front and a full case Detroit Locker in the rear of my FJ40 and I love them. They are totally reliable and you do not have to think about when to engage them. The only very minor downside I can think of would be on a very steep downhill, one wheel can turn faster than the other, but never slower, so there would be a little more control going down hill. Other than that, the Detroit Lockers are bullet proof. I don't have any handling issues at all.

[@proximaone1350]

Hi there I’ve just purchased a 2018 Mitsubishi Pajero Sport with a rear differential locker, this video and your previous video have explained why this bit of kit is important, I’ve previously owned a 94 Holden jackaroo , then a Subaru Forester xt, which is a great car for on the bitumen a light off road duties! I now require a vehicle that will tow biggish vans and reasonable off road ability so the Pajero Sport is a good compromise in my opinion, also it has great fuel economy. Thx for the video I’ve subscribed.👍

[@mtnboy6201]

Always appreciate and trust your good judgment and experience. Keep up the good work !

[@wannabeangler]

I love all your videos! I have an older '99 ram 1500 HD. I have 4.10 gears with positive traction. I rarely use 4LO like you. It's great for 99% of applications. I do mountains and beach wheeling and have it in 4HI which is a 60/40 split. Rarely do I need 25% to each wheel. That's why I am hesitant on buying another vehicle. Solid front and rear is extremely helpful in most conditions. Only drawback is that my truck is a gasser! Would love a diesel in this truck. Thanks again for the informative video.

[@78a67h]

I am an engineer with over 30 years of off-roading experience and I fully support your arguments. Another point is that I believe ARB Air locker would not work in the front axle of an IFS truck because of the fitted half axle rubber boots (bellows) which will not hold the air pressure necessary to make this locker work.

[@JeremyPetho]

The air pressure will not go into the rubber boots, it will stay in the locker's air chamber. If the seals fail and it leaks, the air will go into the differential housing and out the breather.

[@cameronallan3771]

Great video mate you just saved me a fair bit of cash as I have a ifs dmax and I'm doing a locker very soon this just put the nail in the coffin for a rear locker thank you

[@andrewlynch5620]

Thanks, I reasoned that I should get front because I have rear LSD but your logic is solid. Thanks

[@MrAbsentdriver]

I choose two lockers, front and rear. When i flip one, I usually use two. And havnt been stuck in many cases, But of course more money to install

[@claytonvellacott6289]

Half of those points did not even occur to me. Cheers!! definately saved me some pennies!

[@TheOverlandGolfer]

i had just commented in the video about Lockers that i would need to turn so i chose the rear. glad to see your info in the video was spot on

[@428ghost]

Canadian perspective: snow! Front locker is an incredible boost to traction in deep snow. You'll always slip/slide enough on turns not to cause binding while maintaining steering traction. I'm getting a rear locker installed next year. I suspect I'll have that engaged more in summer on rocky trails while using the front locker in winter. Or both if I really screwed things up!

[@wankertoo]

In my opinion Ronnie you are 100% correct, I have both but use them as you suggest. Paul

[@brandonrichter6910]

My take on running the rear locker over front is similar to yours, the main difference being i believe with my rigs (strictly extreme off road vehicles) i have limited slip diffs in my front ends and locked in the rear. i was running 3/4 ton running gear, if i was really binding up in the rocks, i liked the fact the trac-lok would slip instead of forcing the wheel and blowing the caps off the u joint and shearing the ears off the axle shaft. While yes, i still broke, and continue to break axles, i break far fewer. I recently wheeled the truck my lady drives with an open front and wow i broke a lot of parts. The added traction of even a front limited slip made traversing obstacles easier, thus requiring less romping to get up

[@Ronny_Dahl]

Brandon Richter getting a front LSD would be very handy, like your thinking...

[@olliehopnoodle4628]

One of the great debates of our time along with 'ported vs manifold vacuum' and 'carb vs fuel injection'. Thank you Ronny for weighing in on the debate. I don't have any where near the experience that Ronny does but I have to disagree with him on this one. I find my front locker is best for pulling up hills, going over logs, etc. I like his points about expense and going down hill. And, yes, if you can afford a front and rear locker that is the way to go. Going up hills the majority of the weight in on the rear axle. It is less likely to lose traction on either wheel when compared to the front axles. So I often find using the front locker to be the best choice. Yes, the steering can become more difficult but usually usually you are not making big steering adjustments. My jeep has both front and rear lockers but if I had to choose which axle to put a selectable locker in I would probably go with the front.

[@ericcoppola]

Tks . New to 4 wheeling . Very helpful!!!! Just got the rubicon and will be trying it out!!!

[@Kiddomike]

Another informative video for beginners like me! Thank you Ronny! I was thinking on installing air lockers on the 200 series Land Cruiser because it only came with a center diff lock. The 200 series I got doesn't have traction control either, which is why, I think, it will be needing a proper diff lock.

[@didge110]

Excellent Ronnie, thanks very much - I've just been mulling over buying a complete 2nd hand front axle assembly with a locker but don't really do hard core tracks that often and your video has helped same me some serious dough - thanks again. Nice rig, btw :)

[@salvatorecosenza727]

Thank you for the best explanation on front vs rear diff lockers! I have a 1999 Chevrolet k2500 diesel suburban that I special ordered back in 1998. It has every heavy duty option available and no frills. In side is rubber floor mats and vinyl 9 passenger seating with still a huge space behind the last row. It has no electrical options like power windows, seats, etc. Since I used to hall my boat to the ocean with it, and beach launch, it was for salty wet use. It has a 3.73 positraction rear diff, which is much better than limited slip, but it does jerk me around. Now with your recommendations, I won't get that very expensive front locker on the independent diff and go for a manual rear diff locker. It is a long wheel base vehicle with some rear over hang so I stay away from high roll over, but I do climb steep terrain in the woods of U.S. northern Connecticut. Now that it is an "old" truck, I have been more adventurous with it. Thanks again for all you informative videos.

[@beechfox3423]

Salvatore Cosenza Positraction is a limited slip. Gov lock/g80 are lockers.

[@swampdonkey5552]

I went auto locker in the front. Reason being way cheaper than on-off style lockers and by putting it in the front it disengages once the hubs are disengaged... meaning no strange noises while driving on the road. Works well for me and in my opinion the front helps pull the truck over things with my smaller tyres and with IFS it is always the front tyres that will lift therefor without a locker the front is utterly useless once one tyre leaves the ground...

[@davidmoulton5422]

[@Phil_McAvity]

My opinion is: if you've got the money for a rear locker wait & save up$$ to get both installed at the same time as most places will do you a deal when getting it all done at the same time.

[@chrisjanes15]

Great Vid Ronny! Couldnt agree more about the weight distribution especially when tackling hills.

[@Cjramone69]

I just put a front locker in my cruiser last week and we went up the bush here to test it , most gates were shut so i couldn't really test as much as i would have liked , however we found a very steep mud slide the locker was great heaps better than no locker but i reckon this guy is correct about the weight i reckon the traction that i did break was caused by my draws and fridge tools roof tent and stuff , im pulling my rear diff centre out today as i went to ARB and got the back one so after i put it in im going to the same mud slide and try both and together .

[@TytheBandit]

I've got a Jeep Rubicon and have done mud plus rock crawling. 95% of the trips I don't even use the front locker only the rear. Handy in rock crawling straight up on a steep incline is the front. That back is beast.

[@heavypizzas6004]

Jimbo Jones Totally, late model Pajeros have factory rear locker also.

[@albertvella8821]

Totally agree, rear diff is the best to have. Really like your videos they are interesting.

[@98hundy]

Pretty much agree 100%. in my 100 series Land Cruiser I rarely use the front locker for all the reasons mentioned. I'm guessing W Australia is similar to Nevada in terrain.

[@JakeandtheMan]

I live in a part of North America where we have true four seasons, I have seen it all in my 60 yrs, -40c to +35c mud, rocks, sand, forest, prarries, lots of mountains, glaciers, creeks, rivers, ice roads across lakes, 8 foot deep snow, and I agree 100% with rear locker first! and if you got the gold front too. Then we have something that all the lockers, tires, and hp in the world is not going to help you it's called muskeg that can snatch you and suck you in and it does not care what u drive, tanks, bulldozers, 6x6 lightwt. Vehicles with wide extra wide balloon tires for flotation, light wt. track hoes with extra wide tracks, military vehicles, you name it the only vehicle I have NEVER seen get stuck in it was a hover craft. The only way to get into our well sights and service areas is to lay down huge wooden flotation mats and build a road sometimes out of hundreds of them.

[@MdubFrederson]

[@bmorsh]

I have a Jeep TJ 4.0 I6 (6 straight) with 31" tires, I have a front winch (9,500 lbs) + rear LSD on a dana 44. It has a 3" lift. All standard, manual transmission stick shift, 5 gear. My front axle is either dana 30 or 35, I am not sure (need to check). I do not use it for crawling, but I go off the road often, 15% of the time, and I do run into mud and snow often when I am out. My tires are all terrain tires, I do 85% of the driving on the road. It is NOT a daily driver, the Subaru is the daily driver. The Jeep is for outdoors stuff. I have got stuck in deep mud holes a few times, didn't want to stress out the engine too much, maybe if I rocked it or put some momentum. But just as you pointed out in your previous video on diff lockers, as old as my Jeep is, I have kept it in excellent "mechanical" shape and it is structurally solid; I hate to damage it burn out stuff. I end up getting out and use the winch, therefore. I was thinking if I add the front Ox (cable) locker (full locker, not LSD), then maybe I can avoid swimming in mud water as often as I do. How much of a difference does having actual front lockers + rear LSD make to just having the rear LSD?

[@JulianFuller001]

Hi Ronny. I have an NM Pajero with a Torsen LSD. This does not have the normal clutch pack in an LSD, it uses worm gears that bind and essentially turn the rear diff into a spool (basically locked while under torque) so I'd probably put a locker in the front. A Torsen diff can be locked while one wheel is in the air, by ratcheting on the handbrake a few clicks, so no need for a rear locker as this type of LSD is widely regarded as the holy grail of LSDs. Front locker only on this model Paj. Later models have a factory rear locker and previous models have a clutched LSD. Just some interesting trivia. 😊

Only after buying my 80 series landcruiser, that came with both front and rear factory lockers have I had the chance to use them, and yes, totally agree with you on all counts. front locker on most situations is a hassle as a locked 80 series DOES NOT turn, at all, whereas the rear locker can push you out of most situations, unless going uphil on a straight line in a rutted and full of gravel track. then the front locker is a jewel.

[@Ronny_Dahl]

enketamin my exact thoughts and you wont know until you have both lockers.

[@thereelangler2391]

Great Ute! The rear selectable locker is a much simpler solution to the traction equation if you aren't trailering your trail vehicle to the great outdoors. Especially in an over landing truck, you can save a lot of aggravation and money.

[@mithalkaran8068]

I just love the cruiser looks bloody awesome

[@JoshuaWriter]

In the US, the toyota 4runner trd-off-road version comes standard with a rear locker and a-trac for the front. Works wonders.

[@ineedabeerandaliedwn]

Totally agree, I love my rear locker, and my IFS in my Ford F-150 would not survive V8 horsepower and larger tires.

[@richardlangley4241]

Yep!!!👍Totally agree with you Ronnie. talkalot of sense

[@arnoldosuna6462]

I just ordered front and back ARB for my Jeep. I know you guys "down under" don't care to much for jeeps, but that's all we have here in the states. I wish we had the Landcruisers that you guts have there. they are absolutely AWSOME!Cheers Dude!

[@terryturner2833]

dude i have a nice capable cruiser(which is about to get a rear e-locker! yeah!) but hey mate there is a big jeep crew here in OZ .mate i reckon they are fukn cool n capable!

[@CurseMonstr]

They sell the 80 series over there and maybe the 100 series not entirely sure on the 100. 80s are just as capable. Obviously won't get that V8 grunt but can always engine swap.

[@vincebellucci2167]

Great video and information. I learned a lot and am going with a rear locker first. Thanl you.

[@waynelamb6348]

Im about to start Building my dream 4x4 machine and i will install both lockers, we are doing the cape next year and where I want to go I will need them, Love your video's. Cheers

[@mbadagoff]

I also agree, plus you get the benefit of getting rid of your factory limited slip diff and replace it with a selectable locker that is open when not engaged. I believe that an open diff is far more stable on icy or slippery roads if you use your vehicle as a street rig. The rear end seams to want to slide around all the time as both wheels break loose, opposed to one providing directional stability in an open diff. The only factory locker I like is a Eaton gov lock that provides the benefits of a true locker yet the benefits of an open diff at higher speeds. And all mechanically automatic. I think that a front locker is mandatory for rocks because it encourages the tires to climb up the rock rather than the rest of the vehicles tires trying to push against it like a wheel chock. In that situation there cannot be any rotational slip between the tires. Getting over the obstacle easier will be gentler on the drivetrain.

[@eliefrangie3790]

That saved me a lot of research 👍👍

[@ericzuks3210]

I’am getting a rear locker installed on my Triton Twin Cab,feel a lot better now.

[@94SexyStang]

My old F250 has Both! It really needs it....heavy lumbering boat, sinking into the yard Just from sitting a couple days.

[@anoldmaninthewoods2548]

Thank you! Finally, someone has explained Dif Locks to me!

[@h3runs]

Ah the true beauty of youtube; from all the way in Trinidad, thanks for the advice mate. My pickup came with open difffs, so I've been looking at my options to upgrade my 4x4 system. The power in the is great, but I honestly feel like an oaf when I have to use a fair amount of momentum to drive over certain terrain. I'm not too keen on the air lockers due to additional parts aka additional things to purchase/ maintain/ possibly fail, so I'm seriously contemplating getting something from Harrop. Was actually looking into sourcing and swapping in the LSD which came on other trim levels, and get the Harrop locker for the front, but now I think I'll just go with the rear locker and call it a day. Thanks again

[@mks_95al_ghamdi91]

Thanks for the video though. . Regards from Saudi Arabia

[@sethlucc9469]

Thanks Ronny your advise is all ways valuable

[@alnbaba]

My truck came standard with a rear locker and have felt no need of putting one in the front because of the cost. The only times I get stuck is in deep snow and when it hits the frame your only recourse is a shovel and winch.

[@brianmaclennan561]

Im getting a front elocker fitted to my GU, the patrol rear L.S.D's are pretty legendary on there own. I think its all down to what rig you own..

[@georgedunham7311]

Awesome channel mate. So informative, and you shoot very straight. Easy to watch. Proud to be a long time subscriber. Cheers mate

[@Shaker4x4]

I have a Vigo dual cab SR5, KUN26R. An ARB air locker is installed in the rear, so what I would call a hard-lock. On tighter corners, obviously only where traction can give a little, it will still tend to affect steering by pushing the vehicle straight, particularly if the rear axles have weight over them. Forward up a hill is awesome with a rear locker, backward is useless when the vehicle's weight is shifting away from the traction. In any IFS with a front locker, the steering components will be stressed. CV equipment should also be upgraded to handle the additional stresses. It's best to keep the LSD in tight working order. In the rear, for hastle free, low maintence, and smooth action, I'd strongly recommend a new generation Detroit locker. ARB Air lockers are great disengaged on-road, and have their strong points off-road. You can't have it both ways between the two, though generally, the best all-round choice is a Detroit locker, and tyres to suit your needs. I run H/Ts for every day use, and A/Ts for touring/off-road work. I have a 95 series Prado V6 I'd like to put a Detroit locker in the rear of that. It has 32" KM2s on it, not lifted, but still fun as a shopping trolley running over parking bumpers, and in mud obviously :-p

[@davidammunson1292]

thanks bro , that is a question I have contemplated as to which one was of more benefit to me,as I am considering just the one locker cheers.

[@gilbertjones6390]

Thx sir. I’m going to be get both eventually but for now I’ll take ur advice and the my e rear locker.

[@theoverlanddisciple]

Great video, answered all my questions and and gave me a why vs just telling me what to get.

[@rollybuegge5683]

we just did a big fishing trip to Coral Bay and did very well boat fishing and four wheel driving on the windy days, we were about 40 kms north of Coral Bay in and out of bays hill climbs and descents, on one beaches we could not go and further so we turn around and we had to get out of our wheel tracks all of us have winches on our trucks the one without lockers had to be winched out, the only way I got out was to engage front and rear lockers on, just the rear was not enough in the soft sand

[@joeyell5592]

I agree I have a Rubicon and I am the same as him I use rear locker 90% of the time vs front only 10% of the time. Both is very nice but you can get away with rear only more often than not. Front locker makes it very tough to turn and never use it down hill trust me it's sketchy at best when near a cliff.

[@rollybuegge5683]

good and very true comments Ronny, spot on

[@rentalbiscuit8508]

it's also depends on the type of vehicle and terrain though. for most short wheel base 4wds that do rock climbing a front locker will usually be more usefully. you should also take into consideration which axle gets the most flex.

[@djarizona]

I have said that for year the rear locker is the most used and more valued of the two since usually the rear is always carrying more weight and gets more ground contact.
