Overview:

The aFe Pro Series Rear Differential Cover is a premium upgrade designed specifically for Dodge Ram 2500 and Ram 3500 models from 1994 to 2002. Crafted to enhance the durability and performance of your vehicle’s rear differential, this cover offers increased fluid capacity and superior cooling capabilities. Ideal for truck owners who demand reliability and longevity from their drivetrain components, the Pro Series cover helps maintain optimal operating temperatures, reducing wear and extending the life of your differential.

Whether you use your Ram for heavy towing, off-road adventures, or daily driving, this differential cover provides a robust solution to protect and improve your rear axle’s performance. Its finned design and reinforced construction ensure efficient heat dissipation and structural integrity under demanding conditions.

Key Features:

The aFe Pro Series Rear Differential Cover combines advanced engineering with practical features to deliver exceptional performance and ease of maintenance:

• Machined cooling fins cast into the aluminum cover for enhanced heat dissipation
• Increased fluid capacity to improve lubrication and cooling efficiency
• Magnetic drain plug to capture metal particles and simplify fluid changes
• Temperature sensor port (1/8" NPT) for real-time monitoring of differential fluid temperature
• Reinforced ribs integrated into the design for added strength and durability
• Wrinkle black powder coated finish for corrosion resistance and a sleek appearance
• Die-cast A380 aluminum construction for ruggedness and lightweight performance
• Includes an O-ring for a reliable, leak-free seal
• Compatible with stock dipstick—no modifications required despite increased fluid volume
• 2-year limited warranty for peace of mind

Construction & Design:

Manufactured from high-quality die-cast A380 aluminum, the aFe Pro Series Rear Differential Cover is engineered to withstand the rigors of heavy-duty use. The die-casting process ensures precise dimensions and consistent quality, while the integrated cooling fins and reinforced ribs provide both thermal management and structural strength. The wrinkle black powder coated finish not only protects the cover from corrosion and environmental damage but also adds a professional, rugged look that complements the appearance of your Ram’s undercarriage.

The magnetic drain plug is strategically positioned to attract and hold metal debris, helping to prevent premature wear inside the differential. Additionally, the built-in temperature sensor port allows for easy installation of a temperature gauge or sensor, enabling you to monitor fluid temperatures and maintain optimal operating conditions.

Installation & Fitment:

The aFe Pro Series Rear Differential Cover is designed as a direct replacement for the factory rear differential cover on 1994–2002 Dodge Ram 2500 and Ram 3500 trucks. Installation is straightforward and requires no modifications to the vehicle or existing components. The increased fluid capacity of the cover does not necessitate any changes to the stock dipstick, making the upgrade hassle-free. All necessary hardware is included, though the pan gasket, spin-on filter, and pickup screen must be sourced separately.

What's Included:

• Pro Series Rear Differential Cover with machined cooling fins
• Magnetic drain plug
• Temperature sensor port plug (1/8" NPT)
• O-ring seal
• Installation hardware

Ideal For:

This differential cover is perfect for Dodge Ram 2500 and 3500 owners who want to improve the reliability and longevity of their rear differential. It is especially beneficial for those who tow heavy loads, frequently drive off-road, or operate their trucks in demanding conditions where heat buildup can accelerate wear. The enhanced cooling and increased fluid capacity help maintain optimal differential temperatures, reducing the risk of overheating and component failure.
