REAR END UPGRADES

[Junior_97]

What’s up guys new to the forum. I have a 2002 Tahoe 5.3 flex fuel. Looking for a good rear end to upgrade to, currently stuck with the 3:42 and want something more sturdy. Savage yard finds would be fine. Thanks in advance.

Welcome to the forum from Oregon.

When I saw the title I thought you were searching for a new wife or girlfriend.

Are you talking about just the gears or the whole axle assembly. I had an 02 Tahoe and loved my 3.73 gears.

If you are doing the whole axle, I would use the 9.5" 14 bolt semi float axle. If you have 4x4, you will need to do the gears in the front diff as well. Or just bolt in the 3.42 gear 14 bolt semi float at the rear.

Preferably a new axle assembly. I found a 10 bolt with 4:10 and a g80 locker for 450$ but I was told the 12 bolt or 14 bolt are the way to go

I went with Yukon Gear and Axle. I had an authorized dealer/vendor do it so it would have the lifetime warranty.

Complete master rebuild kit
Dura Grip limited slip

You mentioned "sturdy" and that is why I recommended the 14 bolt semi float.

As @1BADI5 said, Yukon Gear is a great source for re-gearing kits but like @Doubeleive said, Eaton Detroit Tru-Trac is an excellent choice.

May I ask how much that ran you?

Go to LKQOnline and look for 14-Bolt Saginaw 9.5" axles (RPO AXN) in RWD Escalades and Denalis (2007-2014), they all have 3.42 gears and G80. Just bought one for $289 plus tax but every area is different. LKQ even warrants it. So you have to tell them yours has a 9.5 with 3.42 gears.

We'll eventually install 3.73s in ours.
