USA Standard Gear Differential Master Overhaul Rebuild Kit for 1999-2008 GM 8.6" Differential

Great set! Used in 03 Silverado 1500 2wd.

Just what I needed to put my rear axle back together. Worked great everything fits perfectly. The kit included everything that you needed for the replacement of the rear gears on the axle right down to the marking grease.

Perfect fit, and a fraction of the price of box stores for the same product.

This kit was absolutely problem free. The entire Remove and Replace (R&R) procedure was flawless. I shal order all parts from this sight from here on in. Thank You Amazon& USA Standard Gear. 😉

Arrived really fast I loved that they send it through UPS and didn't have to wait all day Great product

I am happy with this kit and its pricing. The bearings and races were Koyo, a top quality bearing manufacturer. The carrier bearings were USA and the pinion bearings were Japan. The kit came with left hand threaded ring gear bolts, though I didn't use (need) them. It came with several pinion shims and a set of sandwich shims from the carrier bearings. It also came with a differential cover gasket, crush sleeve, thread locker, 1-1/4" pinion nut, a pinion seal, gear marking paint and a brush. It even had a little instruction booklet, but it was pretty general information. It had information about pinion pre-load specs, but from what I found on the internet, the specs provided were on the low side. So check the FSM for what GM has to say on the issue, if you can find one. I found that diluting the paint with one part paint and three parts gear oil worked very well. It was every thing in the picture, plus the gasket. Shipping was priority mail and I had it in three days of ordering. Its a nice, quality kit packaged on a shrink wrap type of blister board so that things don't bang against each other in shipping.

Great quality

Ordered this kit for a 2004 Yukon XL 1500 4WD. Though it says it’s the correct kit for my rear end the rear inner bearing and race were not correct. Everything else is right except those 2 pcs. After using the AI ask a question “Rufus” agrees that others had the same issue as I did with this kit. My mechanic and me had to search around locally to find the correct bearing and race. Leading to 1.5 extra days of downtime on vehicle and more fees on time spent. It’s not like I can just package up what’s not used for an Amazon refund on a whole kit. Or can I? Buyer beware! If I was to do it again I would buy the Yukon Gear kit over this one.

I'm happy with this kit as it had everything I needed to fix my rear differential on my truck and get it up and running again. The bearings and components seem to be of good quality. I'd recommend.

This kit worked for my truck. Had all the parts necessary

Worked well for my use

Good but I return it because I want front This one is rear one

The installer said this was a really good kit and everything went together really well.
