Direct fit in a great part highly recommend I have a 2015 Cadillac ATS and this was an exact fit to my car highly recommend! I have to change fluid after 500 miles for brake in. Will write updated review after!

It's the same as the OEM differential. These aren't very difficult to install yourself. You just have to get past the weight (~80 pounds). Or you can have a mechanic do it for a few hundred bucks in labor. Being cast iron, it probably wouldn't hurt to get a can of rubberized undercoating, and spray it before installation. Otherwise the cast iron will start rusting.

Been looking for this over 2 years now from Cadillac,they say it’s on back order since 2021,couldn’t find this been searching over 2 year,I went on Amazon and I found this ,even though it’s not the original GM parts,but I bought this ,I show the mechanic and he said this will work ,and it did,over 2 years I couldn’t drive my car,thank you Amazon this part works in my Cadillac

Work Excellent

This is a solid replacement for the Cadillac ATS. Its identical to the OEM part and seems to be a really good quality. The shell is cast iron with enameled paint coating. From what I can see, the price seems to be pretty competitive, however there is no listed warranty for this item so I would take that into account when purchasing. There is only Amazon’s 30 return policy. If you are not installing it yourself, sometimes it could take that long just to get a mechanic to put it in.
