Easy to install
Works great installed in my 1996 k1500. Easy straight forward. Got rid of my one wheel peel in my plow truck now have posi. The carrier bearings that came with this work didn't need different ones

2004 Chevy Silverado 1500
I used this posi in a 2004 Silverado 1500 with 4.56 gears. The posi unit works like a dream, but be advised the supplied carrier bearing races had a smaller diameter than the factory ones and will not fit. After purchasing different bearings the unit works very well.
