B&M Cast Aluminum Differential Covers are 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.
