Description
The aFe POWER Pro Series Rear Differential Cover is engineered for maximum strength, cooling efficiency, and serviceability for 2017–2023 Ford Super Duty F-250 and F-350 trucks equipped with the 6.7L Power Stroke diesel engine and Dana M275 14-bolt rear axles.
Manufactured from high-strength A356-T6 cast aluminum, this Pro Series differential cover delivers exceptional durability and impact resistance over factory stamped steel designs. Integrated reinforcing ribs enhance structural rigidity, while the black powder-coated finish with precision-machined cooling fins provides superior corrosion resistance and a bold, performance-driven appearance.
Designed for demanding towing and heavy-duty use, the cover features internal and external cooling fins that increase surface area to effectively dissipate heat from the differential oil. At the factory-calibrated fill level, the Pro Series cover increases gear oil capacity to approximately 5 quarts, compared to roughly 4 quarts with the OEM cover—helping maintain stable operating temperatures and improved lubrication.
For advanced protection and ease of maintenance, this cover includes magnetic drain and deep-reach magnetic fill plugs that capture metallic debris and contaminants before they can circulate through the rear end. A large oil level sight glass, combined with a 1/8" NPT calibration plug preset to the factory fluid level, allows for quick visual inspection while eliminating the risk of accidental overfilling.
All required mounting hardware is included for a hassle-free installation, making this cover a premium upgrade for performance-focused and work-ready Super Duty trucks alike.
When engineering for power, performance, protection, and value, aFe POWER remains the trusted choice.
