PPE 338051120 10.25"/10.5" Cast Aluminum Rear Differential Cover - Black

The Pacific Performance Engineering (PPE) Heavy-Duty Cast Aluminum Rear Differential Cover (338051120) is designed to improve durability and thermal management for the rear differential on Ford Super Duty applications. This cover replaces the factory-style stamped steel unit with a stronger cast aluminum design that helps control heat and protect internal components during towing, hauling, and daily driving.

Cast from high-strength aluminum, the cover features internal heat-dissipating surfaces and external cooling fins that increase surface area for better heat rejection. Improved cooling helps maintain proper gear oil viscosity, reducing wear on gears and bearings and extending differential service life under heavy loads.

For added protection and ease of maintenance, the cover includes a magnetic fill plug to capture metal debris circulating in the gear oil. Designed as a direct bolt-on replacement, this PPE differential cover installs easily on compatible rear axles without modification.

Features:

• Heavy-duty cast aluminum rear differential cover
• Improves differential oil cooling and heat dissipation
• Internal heat sinks with external cooling fins
• Magnetic fill plug captures harmful metal particles
• Helps extend gear and bearing life
• Direct bolt-on installation
