Keep Your Rear End Cool When It Counts

When you're hauling, towing, or just pushing your truck hard, heat is the last thing you want building up in your differential. The PPE 338051020 Heavy-Duty Deep Rear Differential Cover was made for serious Ford owners who know the importance of keeping things cool and clean under pressure. Designed for 1990–2025 Ford F-250 and F-350 trucks running 10.25 or 10.5 inch axles, this cover gives your rear end the protection and performance it deserves. Its tall external cooling fins, the tallest in the industry, work overtime to shed heat, especially when you're pulling weight or taking on long highway runs. It also adds fluid capacity, helping extend gear life and keep everything running smooth. The sleek black finish looks tough while also holding up against the elements. This isn’t just a dress-up piece, it’s a dependable upgrade that backs up your truck’s hard work.

Engineered To Defend Against Heat And Debris

Built from rugged cast aluminum, the PPE 338051020 cover does more than just look good, it solves real-world problems faced by hardworking differentials. The housing features both internal heat sink baffles and oversized 3/4 inch external fins to increase surface area and improve heat dissipation. By holding more oil and keeping it cooler longer, it reduces friction and wear, especially under heavy use. A key highlight is PPE’s exclusive Neodymium magnet-equipped fill plug, which pulls damaging metal particles right out of the fluid before they can reach the gears or bearings. That added layer of protection helps maintain cleaner oil and reduces long-term wear. The cover fits non-dually F-250 and F-350 models and supports both 10.25 and 10.5 inch Sterling axles, including select Excursion builds. From construction sites to cross-country hauls, this is a serious upgrade for anyone who depends on their drivetrain day in and day out.
