Keep Your Differential Cool When The Work Gets Hot

If you're the type who pushes your 2015-2022 RAM 2500 or 3500 to its limits, whether it's hauling, towing, or long highway drives, this PPE HD Front Cast Aluminum Differential Cover is built to keep up. It’s designed to help your differential stay cooler under stress, which means smoother performance and longer component life. Made from high-quality cast A356.0-T6 aluminum, this cover doesn’t just look tough, it is tough, and it works hard to pull heat out of your gear oil. With internal heat sinks and large external fins, you’re getting a serious upgrade in heat dissipation that actually makes a difference when temperatures start climbing. Cooler oil means better lubrication, and better lubrication keeps your bearings and gears protected. Add in a fill plug that houses a powerful Neodymium magnet and you’ve got another line of defense pulling metal particles out of your fluid before they can do any harm. It’s not just about adding a cover, it’s about giving your truck the protection it deserves.

Built For Strength And Engineered To Perform

The PPE 238042000 differential cover brings serious engineering to the front end of your RAM 2500 or 3500. Its cast A356.0-T6 aluminum construction offers superior durability while also functioning as a massive heat sink to reduce fluid temperatures. Internal heat sinks increase contact with oil inside the housing, while external fins expand the surface area, helping shed heat faster than a standard stamped cover ever could. By reducing thermal stress on your differential fluid, this cover helps maintain consistent lubrication, which reduces wear during high-load conditions. The included Neodymium magnet in the fill plug is a smart touch, capturing harmful metal shavings that would otherwise circulate and damage gears and bearings over time. It’s designed to be a direct fit for your application, so there’s no guesswork when installing. With both cooling and contaminant control in mind, this cover is built to help your drivetrain last longer and perform better.
