aFe Street Series Rear Differential Cover Black w/ Machined Fins 19-20 Ram 2500/3500
aFe Power Pro Series Rear Differential Cover
Upgrade the protection and performance of your rear differential with the aFe Power Pro Series Rear Differential Cover. Designed for heavy-duty use, this cover replaces the factory unit with a durable cast aluminum housing finished in black powder coat with machined cooling fins for improved heat dissipation and a bold performance look.
Engineered to fit axles using a 14-bolt pattern, the cover features internal and external cooling fins that help reduce differential fluid temperatures under towing, hauling, or off-road conditions—supporting longer fluid life and improved drivetrain durability.
Serviceability is improved with dual magnetic drain and fill plugs that capture metal particles, helping protect internal components while making fluid changes easier. An integrated oil level sight glass and calibrated fill location allow for quick visual checks and accurate fluid filling without guesswork.
Built for truck owners who demand durability, cooling efficiency, and clean aesthetics, the aFe Power Pro Series Differential Cover is an ideal upgrade for work trucks, tow rigs, and performance applications
