Excessive heat can degrade the protective qualities of differential fluid, leading to accelerated wear of gears and bearings. In limited-slip differentials, constant high temperatures break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control. The PPE Rear Differential Cover for the Ford 9.75-inch 12-bolt axle under 1994-2026 F-150 and 1997-2002 Expedition is cast from high-grade A356.0-T6 heat-treated aluminum alloy, adds 0.43 quart of fluid capacity, and is finished in brushed.
External cooling fins pull heat out of the fluid and add impact resistance, while precision-placed internal windage scrapers keep fluid distributed around the gears and cut the excessive churning that causes heat, aeration, and parasitic power loss. Together the fins and scrapers form an ultra-strong cross-bracing structure, backed by cast-in gussets that support the differential housing flange. The fill plug sits at the factory level, and both service plugs carry high-temperature neodymium magnets to capture ferrous particles.
