So far so good! Installed with Yukon 3.73 gears in a 2nd gen Camaro. 👌 Holding up good with my LS swap.

Nice little unit. I have both, 30 and 28 spline units. 30 spline carrier is a performance upgrade. You will need performance axles, and then those axles will probably use 1/2-inch wheel drive studs. Not a problems for most aftermarket aluminum wheels. The 28 spline is an excellent stock replacement. No modification needed, but both carriers will need different carrier bearings similar to Ford 9-inch. I recommend Timken 'SET47'.

Great product. Installed in my 87 Chevy 4x4 and I am very happy with it. Haven't driven it alot yet but it is working perfectly. No grabbing on turns or popping. Be sure and use the additive when filling with oil. I have used these units before and have had very good luck with them. If you don't know how to set up a differential don't attempt it. Find someone that does.

Good product. Have about 800 miles on since install with no issues. Although the description needs to include that oversize bearings are required for my GM 8.5" 10 bolt application. Having to order the need bearings pushed back completion by a week. But it works well now that it's all in

Bought this for a lot less than I expected. Very quiet I don’t hear it at all.

My box was open and the part was unwrap and it has no paperwork from Yukon gear axle. I would have though that it came with thw paperwork and instructions, but they wasn't there

So far this posi is great. Surprisingly quite and the best bang for the buck. I did add the recommended additive and I suspect that helps. I would buy it again. Huge improvement in traction in my hot rod.
