Auburn Gear Pro Series positraction for GM 8.2" (Buick, Oldsmobile, Pontiac) for 3.31 and up
The Auburn gear limited slip uses a long-proven cone design to provide traction for performance and off-road applications. Auburn warranties their units for one year against manufacturing defects. These units are non-rebuildable. All Auburn Gear positractions come with a bottle of friction modifier. This case is drilled for 3/8" bolts. Some factory gears use 7/16" bolts. If your factory gear uses 7/16" bolts you will need to drill out the ring gear bolt holes.
