I would pull front shaft if you're going to only do the rear, to be on safe side.


Talk to ron (he's one of our vendors) GREAT prices on gears/true-tracs. Labor however, is lil more money.

You could try junkyard searching for a 4.10 equipped front diff from a Z71, save some money that way.

Thanks for all the info. I'm going with tru-trac and 4.10's

Planning on doing the install myself. Any tips r tricks I need to know.

Yes, pull front shaft.

X2 on a factory 4.10 diff. Not a z71, but a V-max truck. They had 4.10's, i don't believe a z71 ever came above 3.73.

As of tips, get a few extra crush sleeves and take your time. Start out using your stock shims on the pinion and carrier if you can. Went from 3.42's to 4.10s with a yukin posi. Used the stock .035 pinion shim depth (new shim) and even got lucky by using the stock carrier shims. Came in at around .007/.008. Not 100% sure, it was a few months ago.

There is also a trick to the pinion preload. Once you think you have it, put a 1/2 breaker bar on the pinion nut at horizontal, let it go and is should fall at a medium rate. How Chris did mine and never made any noise

thats vary by weight of the breaker bar. but itd be close enough

There were plenty of Z71 and even 4x4 non Z71 1500 trucks with 4.10s. I've even seen them in Suburbans and Tahoes.

Auburn Gear makes an awesome limited slip differential with a torque lock feature. And they really last. If you want the benefits of limited slip with trutrac locking when you want to gouge the floor with the gas pedal, they are a good choice.
