Give your 2017-2022 SuperDuty the upgrade it deserves with the PPE Heavy Duty Cast Aluminum Rear Differential Cover for the Dana M275.
Available in Raw, Brushed, or Black finishes, this cover is built to outperform your stock stamped steel cover in every way, cooling, durability, and efficiency. Cast from rugged A356-T6 heat-treated cast aluminum, this cover is designed to handle the toughest conditions. Deep external cooling fins maximize heat dissipation, keeping your fluid at optimal temperatures and extending the life of your gears. Inside, precision engineered fluid windage scrapers reduce churning, heat buildup, and power loss by ensuring efficient lubrication distribution. For added strength, triangulated gussets reinforce the gear housing, reducing flex under load. To keep your differential fluid clean, PPE equips this cover with billet stainless steel service plugs featuring high powered neodymium magnets, capturing harmful metal particles before they can cause wear and damage.
Whether you're towing, hauling, or hitting the trails, this PPE differential cover delivers superior cooling, performance, and longevity. Choose from Raw for an industrial look, Brushed for a sleek machined finish, or Black for a stealthy, aggressive style.
