# aFe Street Series Rear Differential Cover Raw w/ Machined Fins 01-18 GM Diesel Trucks V8-6.6L (td)

aFe Power's new rear differential cover brings performance engineering to the protection of your axle's differential.

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.
