Improved Protection and Smarter Cooling for Heavy-Duty Rigs

If you’re putting serious miles or heavy loads on your Super Duty, your rear differential deserves more than a basic stamped steel cover. The PPE Cast Aluminum Rear Differential Cover for 2017–2025 F250 and F350 trucks with the Dana M275 axle offers a true performance upgrade that helps extend gear life and improve durability. It’s built from premium A356.0-T6 cast aluminum, a material known for strength and excellent heat dissipation. This version adds 0.8 quarts of extra fluid capacity, and with its half-inch thick external fins, the cover helps lower operating temps when you're towing, hauling, or working in hot conditions. Less heat means less breakdown of the gear oil, which helps preserve bearings, seals, and clutch packs in limited-slip setups.

Durable Brushed Finish and Thoughtful Engineering Throughout

The brushed aluminum finish strikes a balance between clean looks and practical durability. It resists corrosion, hides light grime better than polished or raw finishes, and blends nicely with both stock and upgraded driveline components. But this cover isn't just about appearance. Inside, precision-placed windage scrapers reduce fluid churn and aeration, helping maintain steady pressure and minimizing power loss. The entire unit is cast with exceptional dimensional accuracy using steel molds, and features cast-in gussets for added structural support. Service is straightforward thanks to magnetic stainless steel fill and drain plugs with high-temp O-rings. Installation is a bolt-on process with basic tools, and fitment is specific to the Dana M275 14-bolt axle, so make sure to confirm your ring gear size before ordering. If you're looking for a smart upgrade that adds both form and function to the rear end of your truck, this PPE cover delivers.
