Need to strengthen your rear end while improving heat control under heavy use? The PPE Cast Aluminum Rear Differential Cover for AAM 10.5/14-bolt applications is designed to reinforce the factory differential housing and help reduce fluid temperatures for better long-term durability. Factory-stamped steel covers don’t do much for heat dissipation, which can lead to higher operating temperatures and increased wear on gears and bearings when the truck is working hard. This upgraded PPE cover increases fluid capacity and improves thermal efficiency, helping keep differential temperatures more stable during towing, off-road use, and sustained highway driving with heavy loads.
Built from A356.0-T6 heat-treated cast aluminum, this differential cover is engineered for maximum strength, rigidity, and heat dissipation in demanding applications. Deep external cooling fins help pull heat away from the housing more efficiently. The reinforced cast design helps reduce housing flex under load, adding durability in high-stress situations. Increased fluid capacity further improves thermal stability and extends gear oil life. Precision-machined sealing surfaces, integrated magnetic drain-and-fill plugs, and corrosion-resistant construction all contribute to long-term reliability. Designed as a direct bolt-on upgrade, it installs using factory mounting points for a clean, straightforward improvement in both protection and cooling performance.
