    Mainly Red, and the shop that is installing them really recommends them, said that he installs them in all of the county cop cars. heard anything bad about them?

    no banging, clanging or jerking around when it locks or unlocks. A very smooth running diff. I wish I would have went with the Pro series but didn't know that they work on the OBS trucks with different bearings until just recently. Another nice thing about them is that if you wear one out they have a D-rex program to replace the unit for about $150 or less.

    Yeah the D rex was the final selling point,but just a little worried about the DD driving.

    Why are you worried about DD driving? Your truck should drive completely normal. Only put the basic rear end oil in there--do not use a synthetic type of fluid. The Auburn uses clutches to engage the LSD.

    Yeah, Auburn uses cone shaped clutches instead of flat plates. Their instructions say specifically to use only dinosaur oil and GM friction modifier(whale oil) with their LSD.
