aFe Powers new front-end differential cover brings performance engineering to the protection of your trucks front-end. This differential cover has a 3-1/2 quart lube capacity (factory cover holds 2-1/2 quarts) at the factory fluid level line, a magnetic drain plug and a magnetic fill plug to remove unwanted debris. Built-in external fins transfer heat from the fluid to the outside air for maximum cooling. aFe has also designed a large oil level sight glass with calibration plug set to the factory fluid level to eliminate overfilling. This differential cover is constructed out of durable die-cast A380 aluminum with reinforced ribs and a wrinkle black powder-coating for maximum strength and style. When it comes to engineering for power, performance, protection and value, aFe Power is the only choice.
