aFe Power Pro Series Aluminum Rear Differential Cover-Black; 46-71000B

aFe Power's new rear 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 a black powdercoated finish with machined fins for maximum strength and styling. This cover comes with all necessary hardware for easy installation. The Pro Series differential covers include a oil level sight glass. 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.
