PPE Heavy-Duty Cast Aluminum Front Differential Cover

2003–2013 Dodge Ram

238041020

Overview:

The PPE Heavy-Duty Cast Aluminum Front Differential Cover is engineered specifically for Dodge Ram trucks from 2003 to 2013. Designed to enhance the durability and thermal management of your front differential, this cover is an essential upgrade for owners who demand reliable performance under heavy loads or extreme conditions. By improving heat dissipation and increasing fluid capacity, it helps protect your differential’s internal components from premature wear and failure.

Ideal for off-road enthusiasts, heavy-duty haulers, and anyone looking to extend the life of their front differential, this cover offers superior protection against heat-related damage and mechanical stress. Its robust construction and advanced features ensure your differential operates efficiently, maintaining optimal traction and power transfer.

Key Features:

This PPE differential cover incorporates several innovative design elements to maximize performance and reliability:

• Cast from high-grade A356.0-T6 aluminum alloy for exceptional strength and corrosion resistance
• Increases fluid capacity by 0.9 quarts, improving lubrication and cooling
• Half-inch external cooling fins enhance heat dissipation for long-lasting thermal management
• Built-in windage scrapers reduce fluid churning, lowering heat buildup and parasitic loss
• Strong cross-bracing structure formed by vertical fins improves load distribution and impact resistance
• Precisely positioned factory-level fill plug for easy maintenance
• High-temperature-rated neodymium magnets in both fill and drain plugs capture ferrous particles to protect gears and bearings

Construction & Design:

The cover is crafted from premium A356.0-T6 aluminum alloy, known for its excellent strength-to-weight ratio and resistance to corrosion. This material choice ensures the cover withstands harsh environments and mechanical impacts without adding unnecessary weight. The half-inch external cooling fins significantly increase the surface area, promoting efficient heat transfer away from the differential fluid.

Inside, the integrated windage scrapers are precisely engineered to control fluid movement around the gears. By minimizing excessive fluid agitation, these scrapers reduce heat generation and improve power transfer efficiency. The vertical fins also act as structural reinforcements, enhancing the cover’s rigidity and ability to absorb impacts encountered during off-road driving or heavy-duty use.

Installation & Fitment:

The PPE Heavy-Duty Cast Aluminum Front Differential Cover is a direct bolt-on replacement for the front differential cover on Dodge Ram models from 2003 through 2013. Installation requires no modifications, making it a straightforward upgrade for DIY enthusiasts or professional mechanics. The factory-level fill plug location ensures that fluid changes and top-offs remain convenient and mess-free.

What's Included:

• Heavy-duty cast aluminum front differential cover
• Fill plug with high-temperature neodymium magnet
• Drain plug with high-temperature neodymium magnet
• Installation hardware
• Detailed installation instructions

Ideal For:

This differential cover is perfect for Dodge Ram owners who frequently tow, haul, or drive off-road and need enhanced protection against heat and mechanical stress. It is also well-suited for those upgrading their truck’s drivetrain components to improve reliability and longevity under demanding conditions.
