2017-2025 Powerstroke 6.7L PPE Differential Cover Rear (338051800)
Excessive heat can degrade the protective qualities of differential fluid, leading to accelerated wear of gears and bearings. In limited-slip differentials, constant high temperatures can break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control.
Cast from high-grade A356.0-T6 aluminum alloy, the PPE differential cover adds 0.8 quart of fluid capacity and features half-inch external cooling fins for long-lasting heat management and performance.
Built-in windage scrapers inside the PPE cover ensure precise fluid distribution around the gears. By reducing excessive fluid churning, these scrapers lower heat buildup and minimize parasitic loss, promoting more efficient power transfer. Together with the vertical external fins, they form a strong cross-bracing structure that improves load distribution and enhances impact resistance.
The fill plug is precisely positioned at the factory level. Both the fill and drain plugs feature a powerful, high-temperature-rated neodymium magnet that captures ferrous particles for added protection.
Fitment Note
Make sure to order the correct differential cover for your application. The diff covers on the DANA M275/M300/M315 axles look very similar, all with 14 bolts. Verify ring gear sizing before ordering.
