AFE Power's rear differential cover brings performance engineering to the protection of your axle's differential. This differential cover is constructed out of durable die-cast A380 aluminum with reinforced ribs for maximum strength. This cover comes with all necessary hardware and includes an O-ring for a leak-free seal.
Built-in Internal/External Fins: Built-in internal and external fins transfer heat from the fluid to the outside air for maximum cooling.
Magnetic Plugs: This system incorporates a magnetic drain and deep reach fill plug to capture loose particles for maximum protection. Also included is a 1/8" NPT calibration plug that is set to the factory fluid level which eliminates accidental overfilling.
Oil Level Sight Glass: A pre-installed oil level sight glass allows for quick and easy oil inspection.
