Key Features:

The aFe Pro Series Rear Differential Cover integrates advanced design elements and premium materials to deliver lasting performance and protection:

• All-aluminum construction for enhanced strength and corrosion resistance
• Cast-in cooling fins increase surface area to dissipate heat effectively
• Increased oil capacity improves lubrication and thermal management
• Durable black powder coat finish with precision-machined fins for a sleek, rugged appearance
• Dual neodymium magnetic plugs capture metal debris to protect gears and bearings
• Large oil level sight glass allows easy monitoring of fluid levels without removal
• Calibration plug set to factory oil level prevents overfilling during maintenance
• Includes 4 quarts of PRO Guard D2 Synthetic 75W-90 gear oil formulated for high-performance applications
• Compatible with AAM 11.5, 11.8, and 12.0 axle assemblies found in Ram trucks

Construction & Design:

The Pro Series differential cover is crafted from durable cast aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. The black powder coat finish not only provides a tough protective layer but also enhances the cover’s aesthetic appeal with a refined, machined look. Integrated cooling fins are cast directly into the cover, maximizing heat dissipation by increasing the surface area exposed to airflow. This design helps maintain lower operating temperatures, which is critical for prolonging the life of differential components under heavy loads or extreme conditions.

Attention to detail is evident in the inclusion of dual neodymium magnetic plugs, which efficiently attract and hold metal particles suspended in the gear oil, preventing abrasive wear. The large sight glass offers a convenient way to check oil levels and condition without disassembly, while the calibration plug ensures the oil is filled to the precise factory specification, avoiding the risk of overfilling.

Installation & Fitment:

Installation of the aFe Pro Series Rear Differential Cover is straightforward and designed to fit directly onto the factory mounting points of 2019–2020 Ram trucks with AAM 11.5, 11.8, or 12.0 axles. No modifications are necessary, making it a direct bolt-on upgrade. The included synthetic gear oil simplifies the service process by providing the correct lubricant optimized for this application. This cover is an excellent choice for owners looking to upgrade their rear differential protection without complicated installation procedures.

What's Included:

• aFe Pro Series Rear Differential Cover with black powder coat and machined fins
