Key Features

The aFe Power Pro Series Rear Differential Cover combines advanced engineering with practical features to deliver both protection and performance benefits:

• Constructed from heavy-duty cast aluminum for maximum strength and durability
• Reinforced ribs and machined fins enhance structural integrity and heat dissipation
• Red powdercoated finish provides corrosion resistance and a striking appearance
• Integrated oil level sight glass allows for quick and accurate fluid level checks without removal
• Internal and external cooling fins transfer heat efficiently from differential fluid to ambient air
• Magnetic drain plug captures metal particles to protect internal components and extend differential life
• 1/8" NPT calibration plug preset to factory fluid level prevents accidental overfilling
• Includes all necessary hardware for straightforward installation

Construction & Design

The Pro Series M220 Rear Differential Cover is precision cast from high-quality aluminum, chosen for its excellent strength-to-weight ratio and thermal conductivity. The cover’s reinforced ribs provide added rigidity to withstand impacts and harsh off-road conditions, while the machined cooling fins increase surface area to dissipate heat more effectively. This design helps maintain lower differential fluid temperatures, which is critical for preventing premature wear and maintaining optimal performance.

The red powdercoated finish not only enhances corrosion resistance but also adds a durable, visually appealing layer that resists chipping and fading over time. The inclusion of a magnetic drain plug and a calibrated fill plug demonstrates a thoughtful approach to maintenance and reliability, ensuring your differential remains protected and properly serviced.
