aFe Power Pro Series Rear Differential Cover
Upgrade your Ford Super Duty’s rear differential with the aFe Power Pro Series Rear Differential Cover, engineered for enhanced protection, cooling, and long-term durability. This direct-fit aluminum cover increases oil capacity over stock to improve lubrication and help reduce operating temperatures under heavy loads. Integrated internal and external cooling fins promote efficient heat dissipation, while dual magnetic drain and fill plugs capture metal particles to protect critical drivetrain components. A large oil level sight glass with calibration plug allows for quick, accurate fluid checks during maintenance. Finished in a rugged black powder coat with machined fins for an aggressive appearance, this cover includes all necessary mounting hardware and a precision O-ring seal for a secure, leak-free installation. Designed for Ford 10.25" and 10.50" rear axles on F-250 and F-350 single rear wheel applications
