Construction & Design

The aFe Pro Series rear differential cover is precision cast from heavy-duty ¼” thick iron, delivering exceptional strength and durability. This robust material choice ensures the cover can withstand impacts from rocks, debris, and other trail hazards that commonly threaten vulnerable drivetrain components. The cover’s smooth, contoured design minimizes the risk of snagging or catching on obstacles, which helps prevent damage during off-road excursions.

Finished in a durable black powder coat, the cover resists corrosion and maintains its rugged appearance even after extended exposure to harsh environments. The high fill plug is strategically placed to reduce the chance of trail damage, while the calibration plug is factory-set to the correct oil level, simplifying maintenance and preventing costly overfilling mistakes.

Installation of the aFe Pro Series M220 Rear Differential Cover is straightforward and requires no modifications. It is designed as a direct replacement for the factory rear diff cover on Jeep Wrangler JL models from 2018 through 2026 and Jeep Gladiator JT Rubicon models from 2020 through 2025 equipped with the Dana M220 differential. The cover bolts directly onto the differential housing using existing hardware, making it an ideal upgrade for both professional installers and DIY enthusiasts.
