PPE 338051100 Heavy-Duty Cast Aluminum Rear Differential Cover

The Pacific Performance Engineering (PPE) Heavy-Duty Cast Aluminum Rear Differential Cover (338051100) is a rugged upgrade for the rear differential on Ford F-250, F-350, and Excursion trucks equipped with Sterling 10.25" or 10.5" 12-bolt axles. This premium cover is designed to improve heat dissipation and increase fluid capacity, helping your differential run cooler and extend the life of internal components.

Constructed from high-strength cast aluminum, this differential cover features internal heat sinks along with external cooling fins to maximize surface area for efficient thermal control. Lower operating temperatures help maintain proper fluid viscosity and reduce wear on gears and bearings, especially during towing, hauling, or demanding driving conditions.

For added protection, the cover includes a magnetic fill plug that captures harmful metal particles circulating in the differential oil. The bolt-on design allows for straightforward installation on compatible Sterling axles, making this a durable and functional upgrade for both diesel and gas-powered trucks.
