B&M (71506): Cast-Aluminum Differential Cover for Silverado/Sierra 1500

The 71506 cast-aluminum differential cover for AAM 9.5 and 9.76 differentials from B&M strengthens the differential by preventing case distortion and ring gear / bearing cap deflection. Thanks to their military-grade (MIL-A-8625), black-anodized A356.0-T6 aluminum base, these rugged covers significantly increase fluid capacity and quickly dissipate heat to prolong the life of your ring and pinion gears.

You’ll also find an engraved B&M logo, drain and fill port locations, a magnetic drain plug for catching ferrous metal particles, complete hardware, and installation instructions. B&M backs this cover with a Lifetime Limited Warranty.
