Help -- 3.91s from Difftechnics
We are in the middle of swapping out the ring and pinion on my 2005 GTO. I purchased a set of 3.91 from Difftechnics. We are having a very hard time locating the following information:
Pinion Depth Specification: ???
Side Gear Pre-Load Specification: ???
Torque specs for all bolts: ???
Has anyone installed these gears before, or can anyone point me in the right direction to get this information. I just emailed Difftechnics, so possibly they will have some of the info, but it may be a bit before I hear back from them (Australia time).
Any help would be greatly appreciated. Thank you!
