The AFE 46-70010 Street Series Differential Cover brings performance engineering and protection to your rear differential. Constructed from die-cast A380 aluminum, this rear diff cover will fit the AA14-11.5 rear axle found in 2003-2014 Dodge Ram 2500/3500 & 2001-2016 GM 2500HD/3500HD. This cover comes with all necessary hardware and includes an O-ring for a leak-free seal. 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. This cover works great combined with a oil level sight glass 46-90001 or deep reach fill plug with a 6" long magnetic tipped dip stick 46-9000 (sold separately)
