Just did this install on a '86 K-10. Works awesome! However, the install was slowed because the little bolt that holds in the center pin was broken. Ended up drilling into the carrier to the left of the pin. We were able to hold the broken end of the pin while drilling into the broken pin from the right. A little air pressure forced the broken end of the pin out of the carrier. Over all a 90 minute project. No bangs, pops, or other drama while driving on tar. Love it!!

Buying one of these for my k1500 weekend offroad and rescue truck. No more one wheel peel

[@tnoutlaw73]

i have a 1995 buick roadmaster. limited with the LT1. I built it to a 383. it has the ole one tire fryer in it. I just ordered this locker as of yesterday and a set of 373 gears as this is my driver. thank you for this video. it made all this make way more sense

[@hotrodray6802]

Traction = BOOM

[@ianmurphy989]

I got the same but bone stock gonna start adding power very soon. My wife hates the car cuz everytime we're in town I'm frying the right rear tire in Griswold truck. Maybe she will be a little happier when both tires spin.

[@seanjhonson6441]

Awesome vid!! Thanks for sharing info, I’m going to go with a locker on my c10 turbo build! Limited slip is a little to expensive! I won’t be using trans brake or going to track so should last awhile.

[@dinonaccarato2989]

great informative video , well done Alley cat.

[@richardmiller3781]

Thanks, it was very helpful

[@snailturbo1348]

Love the videos

[@mrgmc6314]

Thank you I liked and subscribed.... I'm a average Joe just trying to be self sufficient when it comes to mechanical problems.. your video really saved my ass and thank you soooo much for the quick reply.... I'm searching for the carrier now .... just to be sure as long as I use my ring gear I can use any open load carrier out of any gm 10 bolt 8.6 2000 and newer models with disc brakes... ? Just checking to make sure I keep my gearing correct.....

Hows the spartan holding up? Have one to put in my landcruiser soon.. 🌴

[@deeeeeeps]

Good video - Thanks for letting me know it won't work with Gov-lock.

[@armeddutchman]

How crazy was the guy that invented this?

[@randymack1782]

finally got fed up enough, so I bought a 4wd, to make something a bit more serious, but on a budget, but for mostly use for commute to work, in snow, or to get to my home, which is off road. 1 home is 1 mile from a paved road, primary home is 1/4 mile off road, but up a mountain side, im getting to old to lug propane, gas, groceries up mountain side. when snows on ground, or even in summer time when hard rain, I cant get up driveway. in my past I have had a had a Jeep Cherokee, and a Subaru, and both have failed, both were crushed when a big tree fell tree also got my Honda Accord, my daily driver beater, and a GMC 1 ton 2wd I used to haul gravel with. so no plans to go off road, other than my own yards. we just got a snow 2 weeks ago, it took 10 days before I could get a second vehicle down mountain, I had only parked 1 at bottom. during time when my vehicle was snowed in, I put down payment on truck. my wifes car was only 1 that I had parked at bottom. the 4wd, I havent got yet, a used car lot is letting me do payments, plus I will be doing work to reduce payments. when I get it 1/2 paid, he will let me take it home. its a 1992 Chevy Silverado 4wd with 5 speed. planning to put a cable operated lock to do away with solenoid, and want to make it so I hopefully can get up & down driveway in bad weather? my wife is 67, I am 55, and have back & knee issues, no plans to sell home, cant afford to but another home, & no desire to live near people, and my second home was cheap, belonged to best friend, his family sold it to me dirt cheap, but just a Mobile Home 1 mile into woods, opening up to 10 mile mountain views in backyard. not tried to go there in over 2 weeks, due to weather, will plan to this weekend, but normally stay there 1-3 days a week, & rest of time primary home. so will lunchbox lockers front & rear, plus chains do what I want? maybe???? a decade ago, I had 2 months couldnt drive up or down driveway, I had the Jeep Cherokee, but of course 2 wheels would spin, thats all, never made it but maybe 100+ foot. while I normally park maybe 5 feet off the road when expecting bad weather.

[@oldschool-ef4jz]

Doing a complete rebuild on a 87 Chevy truck , where is the best place to purchase a lunchbox style locker ? Thank you

[@trdrockwarrior_sport4432]

i have a good question do a person install the auto locker in the front and the back???? i have a 2014 tacoma trd sport crew cab 4wd im thinking should i install auto lockers in the front and the back what do you think???

[@Chevyboy-xi7jg]

How much power you putting to it?

[@jamesfranks3267]

Is it something you’d run in a daily driver??

[@robbiegirosky7055]

What way did the c-clip retainers face?

[@foghornleghorn8674]

Was reading they can be a bit dicey on snow or ice roads,

[@hotrodray6802]

Yes. Dont drive like an idiot.

[@pieroarenas9787]

I have a 2001 chevy blazer 4x4. I do go offroad. But nothing crazy, just to have fun maybe twice a fun. I have 31inches tires .. would you recommend just a lunch box?? Or a whole posi locker??

[@kyle123589]

did you use the spider gear shims under the locker?

[@raulburgos6083]

Im just tryna do even burn outs in my 4.3

[@zacheastwood1414]

I have a g80 diff in my 98 k1500 can I put a locker in that carrier

[@lynndragoman1573]

The weak link in any 88-98 10 bolt is the carrier will break under load. Adding the locker makes sure it will break sooner. On a 12 bolt you dont have that problem.

[@anthonypesqueira7540]

Change the carrier to a real locker and use C clip eliminators. No need for a 12 bolt.

[@mattslough4448]

Bought one of these for my 2006 silverado but i can't get all of the pieces to fit in the carrier. Its about ¹/⁸ to wide to fit in the carrier. Thoughts?

[@daleyoung601]

Did you remove "all" the shims from side and spider gears inside the carrier?

[@flscalesplitter]

Question i have a 02 blazer zr2 with the g80 8.5/8.6 rear. If i remove the guts would this work or do I have to put in a basic open carrier. Thx

[@AllieCatCustoms]

You will need a stock open carrier to fit the Spartan locker. Those g80 carriers are specifically made for them

[@flscalesplitter]

@@AllieCatCustoms ok thats what i figured but hey 8.5 open carrier and a Spartan im looking at 350 which isnt that bad

[@johnhosley5468]

Just a question, would it make the install easier to pull the entire differential and install the locker on the bench? I know it's a little more work but would it be better?

[@alliecatcustoms5808]

John Hosley honestly, as simple as it is to install the locker, It would take longer to remove and install the axle than it would to install the locker. Unless there is a situation where you can’t easily get to the axle. I’ve rebuilt many axles without a lift, and if you are gonna install gears, I’d put the axle on the bench if I couldn’t easily sit up strait to work on it.

[@johnhosley5468]

Thank You, I will be REAL close to the ground so I am pull the diff.... Thank you again.

[@johnhosley5468]

Hell I can't just pull the cage can I..... the "C" clips have to be installed before the last parts are put in...….. Correct?

[@ChrisTheMobileMechanic]

@@johnhosley5468 Do not pull the Differential, its is not a remove and reinstall job, you need specialty tools to reinstall it correctly. Jack the rear end up and just take the 20 mins tops to pull the spider gears and install the locker and put it all back together.

[@johnhosley5468]

Thank You Sir.

[@aaronklemm]

Are there aftermarket lockers to replace G80 lockers in new Silverados and Sierras?

[@hotwheelsracer6380]

Im pretty sure you can remove the gov-lock components and install this..

[@hotwheelsracer6380]

But don't quote me on that

[@mattben817]

Do you have to remove the tires and drums ect?

[@AllieCatCustoms]

yes. the axle shafts will need to be moved out of the way to remove and install the locker.

[@mrgmc6314]

I have the g80 in my 2002 Tahoe it blew up so I ordered a lunch box locker to rebuild it .... I put it together to find out way to much slack .... so I looked up this video saw you say it wont work in that case what's my next cheapest option.. . I want to still use the lunch box so now what do I buy a open load carrier for a 8.6 chevy 10 bolt and put the locker in that ?? Fyi it's my family vehicle and I'm on a budget and time crunch ....

[@alliecatcustoms5808]

Mr GMC631 yes, you need an open carrier to install a lunchbox style locker.

[@mrgmc6314]

Please help I cant waste money or time

[@mrgmc6314]

Thank you

[@mrgmc6314]

I'm on the hunt

[@hotrodray6802]

Slack yes

[@mrbigg7255]

👍

[@RandomDude989]

How do you get the c-clips in there too?

[@AllieCatCustoms]

when you are installing C-clips, you will need to install them right after sliding in the outer gear sections. you slide the gear in, slide the shaft through the gear, install the clip, then pull the axle back out, capturing the clip into the outer gear section, then move on to the next step.

[@smokedsalmon1485]

Unless you have to file the clips down

[@madmechanix4962]

@@AllieCatCustoms so on my 12 bolt this procedure is the same.. and before the center part with the springs I would install my axles and C clips then install the center part with the capture pins and then the center rod? And I am done? Or am I missing a step

[@jeremydunn9978]

every video ive watched they do not dhow how they put the passenger side in wtf i cant get it in

[@alexxela8746]

trying find someone that has install in 3500 express, tired of stuck on wet grass or 1" of snow

[@PureCountryof91]

Should be fine. 14 bolt axles are stout and should be what's in your van.

[@frankkron-zq4tf]

You didnt show how to install the c clips on the axles

[@AllieCatCustoms]

I explained that I wasn’t running c-clip axles so I couldn’t show you how to install the c-clips. I showed where they go though. But you install the c-clips after you get the side gears, and center pieces in. The clips will slide in through the slots I showed on the center “clutch” gear, and engage the shaft. Once you get the c-clips slid in place, you can install the center pin, and that will trap the clips in place. I hope that clears things up!

[@Reggied2569]

How do you think it will work with 24 or 26 inch rims on a 72 impala with 373 gears?

[@AllieCatCustoms]

It will work great!

[@497843553]

Does that lsame unchbox locker work for the front 10 bolt

[@hotrodray6802]

Yes

[@TheRowdyJ]

you didnt show measuring the gap to make sure the depth is correct...

[@BIGBADWOOD]

Buy cheep get cheep !

[@madAllan69]

I didn't se any shims

[@PowersPlays97]

Spartan lockers do not require thrust washers/shims they are machined to fit perfectly. Spartan is probably the best lunchbox locker available IMO. Thicker pins ez installation and the springs in the pins aren't exposed as with others like Auburn and Richmond.

[@DaBuGzLiFe]

For the price of this I'd rather get a LSD. There is a cheaper version of this for around 80 bucks.

[@hotrodray6802]

LOL

[@JosephNnbs]

Wouldnt these teeth just wear down from constantly spinning against each other?

[@alliecatcustoms5808]

They don’t really spin against each other with enough force to cause damage. When force is applied they lock against each other and don’t slip. The locker in my video has been ran hard in my street strip c10, and you couldn’t even see any wear on the surfaces.

[@danielaguirre7037]

Horrible video, You talk way too much, and you cut out all the important stuff.

[@theungoliant9410]

So how do you install/ remove c clips with this thing installed?

[@justingomez2379]

I installed mine with out the center spacers they did no fit at all on my dodge dakota..i ended up taking the spacers out on bothsides.se3ms to be working fine

[@yourmom705]

Is it the same on a gm10bolt

[@AllieCatCustoms]

Yes, that was a GM 10 bolt I was working on.
