Description
Enhance the strength, cooling efficiency, and durability of your rear axle with the PPE Heavy-Duty Cast Aluminum Rear Differential Cover, engineered for 1994–2026 Dodge/Ram 1500 9.25″ 12-Bolt axles. Built from premium A356.0-T6 heat-treated aluminum alloy, this precision-cast cover improves oil capacity, heat dissipation, and housing rigidity—ideal for trucks that tow, haul, or perform in demanding conditions.
Designed with half-inch external cooling fins and internal windage scrapers, the PPE cover effectively reduces differential fluid temperatures, minimizes aeration, and optimizes lubrication across all gear surfaces. The 304 stainless steel magnetic drain and fill plugs protect internal components by capturing metal particles, while the cast-in gussets and cross-bracing structure deliver added strength and impact resistance. Whether daily driving or towing at full capacity, PPE’s differential cover ensures consistent performance and long service life.
