aFe Power's new front differential cover brings performance engineering to the protection of your axle's differential. This differential cover is constructed out of durable cast aluminum with reinforced ribs and machined fins for maximum strength and styling. This cover comes with all necessary hardware for easy installation. This cover has about a 2 quart lube capacity at the factory line. Built-in internal and external fins transfer heat from the fluid to the outside air for maximum cooling. This system incorporates a magnetic drain plug to capture loose particles for maximum front-end protection. Also included is a 1/8" NPT calibration plug that is set to the factory fluid level which eliminates accidental overfilling.
