aFe Power's new rear-end differential cover brings performance engineering to the protection of your  trucks rear-end.  This differential cover has a 5 quart lube capacity (factory cover holds 4 quarts) at the factory line, a magnetic drain plug, a magnetic tipped fill plug for maximum rear-end protection.  Built-in internal and external fins transfer heat from the fluid to the outside air for maximum cooling.  aFe has also designed a large oil level site glass with calibration plug set to the factory fluid level to eliminate overfilling.   This differential cover is constructed out of durable die-cast A380-T6 aluminum with reinforced ribs and a wrinkle black powder coating for maximum strength and styling.  This cover fits the AA-14-11.5 axles.

When it comes to engineering for power, performance, protection and value,  aFe Power is the only choice.
