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 AAM 11.5-inch 14-bolt axle found under 2001-2019 GM 2500/3500 and 2003-2018 Ram 2500/3500 trucks is cast from high-grade A356.0-T6 heat-treated aluminum alloy and adds 0.61 quart of fluid capacity for greater thermal reserve, 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.
Features:
- Premium A356.0-T6 heat-treated cast aluminum alloy construction
- Precision cast in permanent steel molds for dimensional accuracy
- Increases oil capacity by 0.61 quart for higher thermal capacity
- 3/8-inch external fins lower differential fluid temperature
- Internal windage scrapers cut churning, aeration, and power loss
- Fins and scrapers form an ultra-strong cross-bracing structure
- Cast-in gussets add housing flange support and rigidity
- 304 stainless plugs with neodymium magnets and Viton O-rings
