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.

5 Quart Lube Capacity: This cover has about a 5 quart lube capacity at the factory line, factory cover holds about 4 quarts.

Built-in Internal/External Fins: Built-in internal and external fins transfer heat from the fluid to the outside air for maximum cooling.

Magnetic Drain Plug: This system incorporates a magnetic drain plug to capture loose particles for maximum rear-end protection. Also included is a 1/8" NPT calibration plug that is set to the factory fluid level which eliminates accidental overfilling.

Optional Accessories Available: Pro Series covers include an oil level sight glass and a deep reach magnetic fill plug for maximum protection. The sight glass and fill plug may be added to the Raw or Street Series covers, see options below.

I just installed this cover yesterday on my '...
I just installed this cover yesterday on my '14 Duramax (Black Fins Pro Series) and it looks awesome. I decided to go with the aFe covers because they were the only covers that have internal cooling fins. I would say about an hour and a half of time spent on the install that includes preparing the new cover. When you first get your cover you will need to clean it, it still has the factory residue and grease in between the internal fins. Another large amount of your time spent will be on removing the factory gasket even with my truck at only 23K miles that thing still fell apart completely. The instructions call for a gasket scraper which I didn't have so I used a cheap kitchen knife, just be sure not to gouge the differential housing. The cover does come with an O-Ring that will replace the gasket however if you want a little more protection you can use some silicone gasket maker outside the O-Ring. (purchase it at your local auto store) The tools you will need are listed in the instructions. On a side note if you plan on keeping your stock size spare tire under the bed aFe includes a ratchet strap to pull it closer to the bumper. I had already removed mine prior to installation which I highly recommend there will be a lot more space to work with.

Sweet cover
Looks great, installed ez. I have a 2005 Ram 2500 quad cab Cummins . It does touch the spare so I used the included strap to hold the spare 2"" away. Works great. Nice to have the bottom drain plug and window to check fluid level.

I will definitely be a return customer.
I was extremely impressed by the quality of the AFE differential cover. And that the kit came with absolutely everything needed for the installation. So pleased that I ordered another one for myself. The parts tech support was spot on as well. Thanks so much for making this a great experience.

Will this cover fit 2016 Ram with the asin trans. Read somewhere it has a different rearend?

The 3500 trucks with the Aisin typically had the 11.8 rear that usually already had a larger capacity finned cover. SA

Yes, both the Dodges and Chevy's used the same rear axle in that year. That cover would work just fine for you. DppSands
