aFe Pro Series Rear Diff Cover Dana M220 for 21-23 Bronco

Upgrade the rear axle of your 2021-2023 Ford Bronco with the aFe POWER Pro Series rear differential cover for Dana M220 axles. This cast aluminum rear diff cover is designed to increase durability, improve cooling, and make gear oil checks easier, all while giving your Bronco a clean, performance look.

Key Benefits

• Stronger housing protection - Constructed from durable cast aluminum to help shield your Dana M220 rear differential from rocks, debris, and off-road impacts.
• Improved cooling performance - Increased oil capacity combined with internal and external cooling fins helps reduce differential temperatures during towing, highway driving, and trail use.
• Clean, corrosion-resistant finish - Black powder coat with machined fins offers long-lasting corrosion resistance and a premium appearance behind your Bronco’s rear axle.
• Cleaner gear oil - Dual neodymium magnetic plugs are used to attract and capture metal particles suspended in the oil, helping to keep the fluid cleaner between service intervals.
• Easy fluid level checks - A built-in sight glass (on this Pro Series design) allows quick visual inspection of differential oil level without removing plugs or hardware.
• Direct-fit design - Engineered specifically for the Dana M220 rear axle found in late-model Broncos for a straightforward bolt-on installation using the factory location.
