Zero stars, terrible product. Yes the cup is beefy but the teeth are half the size as stock and stripped my brand new diff in less than 5 minutes. Diameter is also off and the teeth rattle around. Get the stock cups with a cheap ring like in the picture.

The splines are lot smaller and weaker than factory drive cup. Don’t waste your money on these buy something like vitavon or comparable

Highly recommend these, easy to install, I would be sure to tighten the bolts now and then, they do come loose.
