Fits 2017-2023 Ford F-250 and F-350 Super Duty models (V8-6.7L) equipped with the Dana M275-14 rear axle.

Protect your heavy-duty drivetrain and improve thermal management with the aFe Power Pro Series Rear Differential Cover (MPN: 46-70352). This cover increases fluid capacity to 5 quarts—one full quart over the factory 4-quart system—offering improved cooling and lubricant longevity during heavy towing or hauling. Engineered from die-cast A356 aluminum, it features external cooling fins to transfer heat from the gear oil to the ambient air.

Maintenance is simplified via an integrated large oil level sight glass and a calibration plug set to the factory fluid level to prevent overfilling. For maximum component protection, both the fill and drain ports are equipped with magnetic plugs to capture and remove metallic debris from the gear oil. The assembly is finished in a durable wrinkle black powder coat with machined fins for a rugged, custom look.
