Give Your Rear End The Upgrade It Deserves

If you're pushing your truck hard and relying on it for towing, hauling, or hitting trails, the stock differential cover just won’t cut it. The PPE Heavy Duty Cast Aluminum Rear Diff Cover is a serious upgrade built for real truck owners who want better performance and long-term protection. Not only does it look aggressive and purposeful, but it also adds real function where it counts. With increased fluid capacity and improved heat dissipation, your differential stays cooler under load, which helps preserve oil life and protect expensive components. The built-in cooling fins and internal heat sinks work together to keep temperatures in check, even during heavy use. And the magnetic fill plug is a game-changer, it pulls harmful metal debris out of your fluid before it can do damage. Whether you're upgrading for performance or peace of mind, this cover is a smart investment that works as hard as your truck does.

Designed To Deliver Performance When It Gets Hot

The PPE 338051100 rear diff cover is built from high-strength cast aluminum to provide durability and effective thermal control for your differential. It increases your axle’s fluid capacity, giving your gear oil more volume to absorb heat during extended towing, heavy loads, or off-road driving. Inside the cover, you’ll find strategically placed heat sinks that help draw heat away from the fluid, while external fins allow for improved air cooling during movement. These cooling enhancements help keep your oil’s viscosity stable, reducing the risk of wear to gears and bearings. The cover also comes with a Neodymium magnetic fill plug that captures metal shavings and ferrous particles before they circulate through your system. This added filtration helps extend the service life of your oil and internal components.
