Key Features

This advanced differential cover combines robust construction with thoughtful engineering to maximize protection and cooling:

• Constructed from durable die-cast A380 aluminum for long-lasting strength and corrosion resistance
• Machined external fins increase surface area to dissipate heat efficiently, keeping differential fluid cooler
• Large neodymium magnetic drain plug captures loose metal particles, preventing internal damage
• Increased fluid capacity improves cooling efficiency, especially beneficial during towing or heavy load conditions
• Black powder-coated finish option available for enhanced rigidity and corrosion protection
• Precision-engineered for a direct-fit installation on 2003–2010 Dodge Ram 2500 and 3500 models without modifications
• Includes all necessary hardware for straightforward, hassle-free installation

Construction & Design

The aFe Street Series differential cover is crafted from high-quality die-cast A380 aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. Its rugged design features machined fins that maximize heat transfer from the differential fluid to the surrounding air, effectively reducing operating temperatures. This thermal management is critical for maintaining fluid integrity and preventing premature wear of internal drivetrain components.

The integrated neodymium magnetic drain plug is strategically positioned to attract and hold metal shavings and debris, providing an additional layer of protection by preventing contaminants from circulating within the differential. The cover’s robust construction ensures it can withstand impacts and harsh conditions commonly encountered during off-road driving or heavy-duty use.

Installation & Fitment

The aFe Street Series Front Differential Cover is a direct-fit replacement designed specifically for Dodge Ram 2500 and Ram 3500 trucks from 2003 through 2010. Installation is straightforward and requires no modifications to your vehicle’s existing setup. The package includes all necessary mounting hardware, allowing for a quick and secure installation that can be completed with basic hand tools. This makes it an ideal upgrade for owners seeking improved durability and cooling performance without the need for professional installation or custom fitting.
