Give Your F150 The Cooling And Strength It Should Have Had From The Start

If you have ever pushed your F150 hard and wondered how well your rear end is holding up, this is one of those upgrades that just makes sense. The PPE Heavy Duty Cast Aluminum Rear Diff Cover is built to handle real work, whether that means towing, hauling, or just putting power down more aggressively than stock. With increased oil capacity, your differential has more fluid to manage heat, which helps keep everything running smoother when temperatures start to climb. Additionally, the combination of internal heat sinks and external cooling fins works constantly to pull heat away and keep your gear oil in a safe operating range. That translates to better protection for your gears and bearings over the long haul. The brushed finish gives it a clean, upgraded look that stands out without being over the top. Designed for 1994-2026 F150 models with the 9.75 inch differential, it is a simple upgrade that delivers real benefits every time you drive.

Advanced Aluminum Construction Built To Control Heat And Wear

The PPE 338051310 differential cover is engineered from A356.0-T6 heat-treated cast aluminum, offering a strong and thermally efficient upgrade over the factory cover. This material helps dissipate heat more effectively while also reinforcing the differential housing under load. Inside, integrated heat sinks draw heat away from the gear oil, while the external cooling fins increase airflow across the surface to further reduce operating temperatures. Furthermore, the increased oil capacity allows the fluid to better absorb and distribute heat, helping maintain consistent viscosity during demanding conditions. Internal ribbing adds structural rigidity, reducing flex and improving long-term durability when the drivetrain is under stress. The included hardened billet stainless steel fill plug features a Neodymium magnet that captures metal debris before it can circulate through the system. This added filtration helps protect internal components and extend service intervals. Backed by a limited lifetime warranty, this cover is designed to deliver dependable performance mile after mile.
