Give Your F150 The Protection It Needs When Things Heat Up

If you are putting your truck through real work, your differential deserves more than the thin factory cover it came with. The PPE Heavy Duty Cast Aluminum Rear Diff Cover is built to handle the kind of heat and stress that comes from towing, hauling, or pushing your F150 harder than stock. With increased oil capacity, your gear oil can better manage rising temperatures, helping everything stay smoother and more consistent under load. Additionally, the external cooling fins and internal heat sinks are always working to pull heat away, so you are not relying on luck when things get demanding. The black finish gives it a clean, aggressive look that fits right in with a well-built truck. It is one of those upgrades that quietly protects your investment every time you hit the road. Designed for 1994-2026 F150 models with a 9.75 inch differential, it is a simple change that makes a noticeable difference over time.

Engineered Aluminum Design That Controls Heat And Extends Component Life

The PPE 338051320 differential cover is constructed from A356.0-T6 heat-treated cast aluminum, providing both structural strength and efficient heat dissipation. This material allows the cover to pull heat away from the differential more effectively than a standard stamped steel unit. Inside the cover, integrated heat sinks help draw thermal energy out of the fluid, while external cooling fins increase surface area for improved airflow during operation. Furthermore, the increased oil capacity allows the fluid to better absorb and distribute heat, which helps maintain stable viscosity in demanding conditions. Internal ribbing reinforces the housing and reduces flex, adding durability when the drivetrain is under load. The hardened billet stainless steel fill plug includes a Neodymium magnet that captures fine metal particles before they can circulate through the system. This helps keep the fluid cleaner and protects gears and bearings from premature wear. Backed by a limited lifetime warranty, this cover is designed for long-term reliability and consistent performance.
