The AFE 46-70012 Pro Series Differential Cover brings performance engineering and protection to the rear of your Dodge Ram & GM Duramax Axle. The Pro Series differential cover is constructed out of durable die-cast A380 aluminum with reinforced ribs for maximum strength and styling. Including all necessary hardware with a built-in O-ring this cover makes maintenance a breeze. The Pro Series differential covers include an oil level sight glass as well as a magnetic dip-stick for maximum protection.
This cover increases your lube capacity to 5 quarts. That adds an extra quart over the factory fill with your stock cover. The built-in internal and external fins transfer heat from the fluid to the outside air for maximum cooling. Maintenance and inspection will now be a breeze with the pre-installed oil level sight glass as well as the magnetic drain and fill plug for easy fluid changes.
