Overview
The aFe POWER Pro Series Rear Differential Cover is designed to provide increased strength and protection for the Dana M220 rear axle found in compatible Ford Ranger and Bronco models. Constructed from heavy-duty 1/4-inch thick cast iron, this differential cover provides a substantial upgrade over the factory cover for vehicles used on the street, trail, or in demanding off-road conditions.
The smooth exterior design helps reduce the potential for rocks and other trail obstacles to catch on the differential cover, while the black finish and embossed aFe POWER logo provide a clean, performance-oriented appearance. A high-mounted fill point helps protect the fill plug from trail damage, and an integrated calibration plug is positioned at the factory fluid level to simplify servicing and help prevent overfilling.
Key Features
The aFe POWER Pro Series Differential Cover features heavy-duty 1/4-inch thick cast iron construction for increased strength and durability. Its smooth exterior profile is designed to reduce rock hang-ups when navigating rough terrain, while the high fill point helps protect the oil fill plug from trail impacts. An integrated calibration plug is set at the factory oil level to simplify differential servicing and prevent overfilling. The cover is finished in black with an embossed aFe POWER logo and includes stainless steel mounting hardware for corrosion resistance and long-term durability.
Construction & Design
The Pro Series cover is manufactured from heavy-duty 1/4-inch cast iron and weighs approximately 9 pounds, providing substantial protection for the Dana M220 rear differential.
Rather than using aggressive exterior fins or protrusions that can catch on rocks, aFe designed the cover with a smooth exterior surface for improved clearance over trail obstacles. The raised fill location helps keep the service point protected and accessible, while the factory-level calibration port provides a convenient reference when adding differential fluid.
