Overview:

The aFe Pro Series Rear Differential Cover is a premium upgrade designed specifically for Dodge Ram 1500 (1994–2010), Ram 2500 (1994–2010), and Ram 3500 (1994–2002) models. Crafted to replace the stock stamped steel differential cover, this finned aluminum cover enhances fluid capacity and improves heat dissipation, helping to maintain optimal operating temperatures under demanding conditions. Ideal for truck owners seeking to extend the life of their rear differential, this cover also simplifies maintenance with features like a magnetic drain plug and a temperature sensor port.

Whether you use your Ram for towing, hauling, or off-road adventures, the aFe Pro Series Rear Differential Cover offers robust protection and improved cooling performance to keep your drivetrain running smoothly and reliably.

Key Features:

This differential cover incorporates advanced design elements to maximize durability and thermal management:

• Machined external cooling fins that efficiently transfer heat to the atmosphere
• Magnetic drain plug to capture metal particles and simplify fluid changes
• 1/8" NPT temperature sensor port for real-time monitoring of differential fluid temperature
• Reinforced ribs integrated into the casting for enhanced structural strength
• Increased fluid capacity by 3 to 4 quarts without requiring dipstick modifications
• Durable wrinkle black powder coated finish for corrosion resistance and a sleek appearance
• Oil level sight glass for quick fluid level checks
• Calibration and fill plugs with magnets to trap debris
• 50-state legal with a 2-year limited warranty for peace of mind

Construction & Design:

The Pro Series Rear Differential Cover is constructed from rugged die-cast A380 aluminum, chosen for its excellent strength-to-weight ratio and thermal conductivity. The cooling fins are cast directly into the cover along with reinforced ribs, providing a durable structure that resists warping and damage from road debris or impacts. The wrinkle black powder coat finish not only protects against corrosion but also adds a professional, high-quality look to your vehicle’s undercarriage.

Every detail, from the magnetic drain plug to the temperature sensor port, is engineered for both performance and convenience, making this cover a smart upgrade for serious Ram owners.

Installation & Fitment:

Installation is straightforward and designed to fit perfectly on Dodge Ram 1500 and 2500 models from 1994 through 2010, as well as Ram 3500 models from 1994 through 2002. This cover replaces the factory stamped steel differential cover without requiring any modifications to the vehicle or dipstick. While the kit includes all necessary hardware for installation, the pan gasket, spin-on filter, and pickup screen must be sourced separately. The magnetic drain plug simplifies fluid changes, eliminating the need to remove multiple screws or tilt the cover.

What's Included:

• Pro Series Rear Differential Cover with machined cooling fins
• Magnetic drain plug
• Temperature sensor port plug
• Calibration plug
• Fill plug with magnet
• Installation hardware

Ideal For:

This differential cover is ideal for Dodge Ram owners who demand enhanced durability and cooling performance from their drivetrain components. It is especially suited for trucks used in towing, heavy hauling, off-road driving, or any application where extended differential life and easier maintenance are priorities. Enthusiasts looking to upgrade their Ram’s rear differential with a high-quality, functional, and stylish component will appreciate the benefits of the aFe Pro Series Rear Differential Cover.
