PPE Heavy-Duty Cast Aluminum Front Differential Cover

2013–2025 Dodge Ram 2500 & 3500 5.7L Hemi, 6.4L 392, 6.7L Diesel

Part #: 238042020

Overview

The PPE Heavy-Duty Cast Aluminum Front Differential Cover is a precision-engineered upgrade designed to enhance the durability and thermal management of the front differential on Dodge Ram trucks from 2013 through 2025. Built to withstand the rigors of heavy-duty use, this cover improves fluid capacity and cooling efficiency, helping to protect your differential’s internal components from excessive heat and wear.

Ideal for off-road enthusiasts, towing professionals, and anyone who demands reliable drivetrain performance under extreme conditions, this cover ensures your front differential maintains optimal lubrication and traction control. By reducing heat buildup and mechanical stress, it extends the life of gears and bearings, making it an essential upgrade for Dodge Ram 2500 and 3500 owners.

Key Features

Designed with advanced materials and thoughtful engineering, the PPE front differential cover offers superior protection and cooling benefits:

• Constructed from high-grade A356.0-T6 cast aluminum alloy for exceptional strength and lightweight durability
• Increases differential fluid capacity by 0.41 quarts to improve lubrication and heat dissipation
• Half-inch external cooling fins maximize surface area for efficient heat transfer
• Internal windage scrapers reduce fluid churning, lowering heat buildup and parasitic power loss
• Strong cross-bracing formed by vertical external fins enhances load distribution and impact resistance
• Factory-level positioned fill plug for easy fluid checks and maintenance
• High-temperature-rated neodymium magnets in fill and drain plugs capture ferrous particles to protect gears and bearings
• Direct OEM replacement compatible with Mopar part numbers 68216206AB, 68216206AC, and 68216206AD

Construction & Design

The cover is expertly cast from premium A356.0-T6 aluminum alloy, known for its excellent strength-to-weight ratio and corrosion resistance. This ensures durability in harsh environments and under heavy mechanical stress. The integrated half-inch cooling fins are precision-machined to increase surface area, promoting efficient heat transfer away from the differential fluid to maintain optimal operating temperatures.

Inside, strategically placed windage scrapers control fluid movement around the gears, minimizing excessive agitation that generates heat and reduces power transfer efficiency. The vertical fins not only aid in cooling but also serve as structural reinforcements, distributing loads evenly and enhancing resistance to impacts and deformation.

Installation & Fitment

This PPE front differential cover is a direct bolt-on replacement for Dodge Ram 2500 and 3500 models from 2013 to 2025, including engines such as the 5.7L Hemi, 6.4L 392, and 6.7L Diesel variants. No modifications are required for installation, and it fits precisely to factory specifications. The fill plug is positioned for convenient fluid servicing, and the included drain plug allows for straightforward fluid changes. Installation can be completed with standard hand tools, making it accessible for both professional mechanics and experienced DIY enthusiasts.
