Description

The B&M Racing 10306 Hi-Tek Aluminum Differential Cover is an upgraded replacement designed to strengthen the differential by preventing case distortion and ring gear & bearing cap deflection. Constructed from A356.0-T6 aluminum, this rugged cover increases fluid capacity by 0.50 quarts and dissipates heat faster than the stock unit, prolonging gear life. It includes a magnetic drain plug and load bolts for bearing cap support.
