B&M’s Cast Aluminum Differential Cover for the AAM 9.5 and 9.76 differentials is designed to strengthen the differential by preventing case distortion and ring gear & bearing cap deflection. Constructed of military grade (MIL-A-8625) black anodized A356.0-T6 aluminum, these rugged covers significantly increase the fluid capacity and dissipate heat much faster than the stock factory unit to prolong the life of your ring and pinion gears. Additional features include an engraved B&M logo, drain and fill port locations, a magnetic drain plug for catching ferrous metal particles, and complete hardware and installation instructions. These covers are backed by B&M’s Lifetime Limited Warranty.
- A356.0-T6 Aluminum construction
- Fill plug and magnetic drain plug make it easier for servicing
