1986-2018 F250 & F350 AFE Rear Differential Cover (Machined/Pro Series) w/ Gear Oil

Protection For Your Super Duty's Rear-End

When it comes to Super Duty performance, nobody does it better than aFe. Their Pro Series Rear Differential Cover provides exceptional protection to the rear-end of your Super Duty that you need if you're pushing your truck to the limit by towing, hauling heavy loads or hitting up some extreme off-road trails. With their Pro Series Rear-End Differential Cover, you're not only adding a cool look to your Powerstroke Diesel with its machined finish but an upgraded 5-quart lube capacity as well (factory stock is 4 quarts). This kit system also includes a magnetic drain plug as well as a magnetic-tipped fill plug for efficiency that provides a great way to capture loose particles for maximum protection. The built-in internal and external fins work to transfer heat from the fluid to the outside air for maximum cooling which is essential to any hard-working Super Duty.
