Great Product!
You definitely pay for what you get, and this positrac diff definitely cost a pretty penny in itself and the installation. I offroad a lot and having this diff makes a world of difference when climbing up steep hills with loose dirt. BTW if youre looking to upgrade your gears, I went with 4.11 gear ratio which is a step up from the factory 3.92 ratio. (I run 35's)

Perfect Replacement
I shopped around before buying my replacement axle on American Trucks. It shipped reasonably fast and installed as expected. It definitely looks like a high-quality part. The hardest part of the job was installing the wheel studs. My bent axle is no more and I couldn't be happier.

Yukon dura grip
The install would have been easier if I knew that I needed a special tool for the bearing adjusters for back lash. I went to all the auto parts stores in my area and no one knew what I was talking about, but one auto zone. They were very helpful and found the tool, but I couldn’t wait, so I made my own. After that everything thing went pretty smooth. It was my first time installing a locker and knowing what I know now I probably could do it in half the time. I installed it about three weeks ago and had no problems and completely satisfied!!!
