46-70042

Overview:

The aFe Power Pro Series Front Differential Cover is engineered to provide superior protection and enhanced performance for your Dodge Ram 2500 or Ram 3500 front differential. Designed specifically for 2003 to 2010 models equipped with AA14-9.25 axles, this machined differential cover upgrades your truck’s front-end durability while improving fluid cooling and maintenance convenience. Ideal for truck owners who demand reliability and longevity from their drivetrain components, the Pro Series cover offers increased lube capacity and advanced features to safeguard your investment on and off the road.

Whether you use your Ram for heavy-duty towing, off-road adventures, or daily driving, this differential cover delivers peace of mind by reinforcing a critical component prone to damage and wear. Its robust construction and thoughtful design help extend the life of your front differential under demanding conditions.

Key Features:

The aFe Power Pro Series Front Differential Cover combines innovative engineering with practical enhancements to maximize protection and performance:

• Constructed from durable die-cast A380 aluminum with reinforced ribs for exceptional strength and impact resistance
• Increased lube capacity of approximately 3-1/2 quarts, compared to the factory cover’s 2-1/2 quarts, improving fluid cooling and lubrication
• Built-in external cooling fins that dissipate heat efficiently, helping maintain optimal operating temperatures
• Pre-installed large oil level sight glass calibrated to factory fluid level to prevent overfilling and simplify fluid checks
• Deep reach magnetic dipstick and magnetic drain/fill plugs that capture metal particles, protecting internal gears from wear
• Designed to fit AA14-9.25 axles used in Dodge Ram 2500 and 3500 models from 2003 to 2010
• Requires Dodge Gasket P/N: 5086682AA (not included) for proper sealing

Construction & Design:

The Pro Series differential cover is crafted from premium die-cast A380 aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. Reinforced ribs are integrated into the design to enhance structural rigidity, protecting the differential housing from impacts and deformation. The machined finish not only provides a precise fit but also adds a sleek, professional appearance under your truck.

External fins are strategically incorporated to increase surface area, promoting efficient heat transfer from the gear oil to the surrounding air. This cooling effect helps maintain fluid viscosity and prolongs the life of internal components by reducing thermal stress.

Installation & Fitment:

Installation of the aFe Power Pro Series Front Differential Cover is straightforward and designed to be a direct bolt-on replacement for the factory cover on 2003–2010 Dodge Ram 2500 and 3500 models with AA14-9.25 axles. No modifications are necessary, but the use of the specified Dodge gasket (P/N: 5086682AA) is required to ensure a proper seal and prevent leaks. The included magnetic drain and fill plugs simplify fluid changes and maintenance, making it easier to keep your differential in top condition.

What's Included:

• Pro Series front differential cover (machined A380 aluminum)
• Pre-installed oil level sight glass calibrated to factory fluid level
• Magnetic drain plug
• Magnetic deep reach fill dipstick

Ideal For:

This differential cover is perfect for Dodge Ram 2500 and 3500 owners who want to enhance the durability and cooling efficiency of their front differential. It is especially suited for those who frequently tow heavy loads, drive off-road, or operate their trucks in demanding environments where extra protection and fluid capacity are critical. The Pro Series cover helps maintain drivetrain reliability and reduces the risk of costly repairs caused by overheating or contamination.
