46-71150A

Overview:

The aFe Street Series Rear Differential Cover is engineered specifically for 2019 to 2020 Ram trucks, designed to enhance the durability and cooling efficiency of your vehicle’s rear differential. Crafted from high-quality cast aluminum with a robust red powder coat finish, this cover offers superior protection against harsh driving conditions and extended off-road use. Ideal for truck owners seeking to improve their differential’s longevity and thermal management, the aFe Street Series cover combines increased oil capacity with advanced cooling features to maintain optimal gear performance under demanding loads.

Whether you use your Ram truck for heavy towing, off-roading, or daily driving, this rear differential cover provides peace of mind by reducing the risk of overheating and gear wear. Its precision-machined fins and dual magnetic plugs help keep metal debris out of the gear oil, ensuring maximum gear protection and reliability.

Key Features:

The aFe Street Series Rear Differential Cover integrates several advanced features designed to improve your vehicle’s rear axle performance and durability:

• Durable cast aluminum construction with a red powder coat finish for corrosion resistance and long-lasting durability
• Machined cooling fins cast into the cover to increase surface area and enhance heat dissipation
• Increased oil capacity to improve lubrication and reduce operating temperatures
• Dual neodymium magnetic drain and fill plugs to capture metal particles and protect internal gears
• Large oil level sight glass for easy and accurate oil level monitoring without removal
• Calibration plug set to the factory oil level to prevent overfilling and ensure proper fluid volume
• Designed to fit GMCH 9.5 rear axles commonly found in Ram trucks

Construction & Design:

This rear differential cover is expertly crafted from durable cast aluminum, chosen for its excellent strength-to-weight ratio and superior heat dissipation properties. The cover’s red powder coat finish not only provides a striking appearance but also protects against corrosion and environmental damage. The integrated machined fins are precision-engineered to maximize cooling efficiency by increasing the surface area exposed to airflow, helping to maintain lower differential temperatures during heavy use.

Attention to detail is evident in the inclusion of dual neodymium magnetic plugs, which attract and hold metal shavings and debris that can accumulate in the gear oil, preventing premature wear of internal components. The large sight glass allows for quick visual inspection of oil levels, making routine maintenance easier and more accurate.

Installation & Fitment:

The aFe Street Series Rear Differential Cover is designed as a direct bolt-on replacement for 2019–2020 Ram trucks equipped with GMCH 9.5 rear axles. Installation requires no modifications and can be completed with basic hand tools. The included calibration plug ensures the oil level is set precisely to factory specifications, preventing overfilling and ensuring optimal lubrication. This cover is an excellent upgrade for anyone looking to enhance their rear differential’s protection and cooling without complicated installation procedures.

What's Included:

• aFe Street Series Rear Differential Cover with machined fins
• Dual neodymium magnetic drain and fill plugs
