aFe Power Rear Differential Cover Black with Machined Fins for Select Ford 1986-2026 (6.7L) 46-70022

Fits select 1986-2026 Ford Excursion, F-250/F-350/F-450, and Super Duty trucks (6.7L).

Protect your drivetrain and lower gear oil temperatures with the aFe Power rear differential cover. Engineered for heavy-duty use, this cover features an increased oil capacity over the factory unit and integrated cooling fins. These internal and external fins work together to transfer heat from the fluid to the ambient air, ensuring your gears stay lubricated and cool during towing or high-load conditions.

Construction is centered on durability and ease of maintenance. The cover is cast from high-quality aluminum with a black powder-coated finish and machined fins for a custom look. It includes a pre-installed oil level sight glass for fast visual inspections and a calibration plug set to the factory oil level to prevent overfilling. For maximum protection, dual neodymium magnetic plugs—including a magnetic drain and deep-reach fill plug—capture metal particles before they can damage your gears.
