I ordered the wrong possi spline I paid to have it shipped back and was charged again for having the right one shipped back after I had already paid over $500 for the first one I mistakenly ordered it should have been some sort of return label but nope it wasn't but the spline works great

First off, I would like to say this is a nice kit, however if your a 99-06 gm guy the bearing kit is going to be incorrect. The correct bearing kit is a ra-321-C or you can get away with just changing the carrier bearings to the bigger OD set36 (3.062 OD) the kit comes with a 2.891OD. Been chasing this problem for my mechanic for the last couple of days, just want to make sure that whomever else purchases this kit gets the correct information.

I bought this cause they said it would fit my 04 chevy avalanche z71 but the only thing I could use out of the whole kit was the semi posi unit the bearing and castors were too small as well as the yoke and it's bearings I suggest if you had to do your rear-end to just buy the Yukon semi posi by itself and buy all the bearing and everything else from Napa they were the only parts store that found all the bearing and castor and yoke what a headache the kit will cause u

Good for the money but the bearing to came with the kit was wrong so I had to take them to the parts store and get new ones and nobody told you in the instructions that you have to use dummy bearings to set your pinion dip and the numbers on the opinion you cannot read them So I found some on YouTube and just went with those numbers and I got it within a 1000s

Great price for what you get. Yukon diff is tough and reliable, Richmond gears are good quality and run quiet (when installed correctly) and the bearing kit contains quality components. I’d buy again in a heartbeat. For the do-it-yourself mechanic. No gears and/or bearings run quiet and smooth when installed incorrectly...don’t hammer on bearings (False brinelling) and make sure the gears are set up properly!

This kit was installed in 1994 GMC that we had just installed 350 SBC and the stock 3.04 was way too high. The installer said this had the best instruction he has seen in any kit and he has been in the auto repair business for over 30 years. it all went together just fine. have an extra crush ring just in case you go too far. would buy again. and it does have a whine but I can live with that. both tires smoke now....
