The obvious feature of this Mag-Hytec differential cover for '03-'13 Dodge Ram 2500/3500 trucks equipped with American Axle 14-11.5 differential cover is the sight glass. Use it to check the fluid level and fluid condition at a glance.

Since it is a Mag-Hytec unit, it has magnets at the fill and drain plugs as well as a 1/8 NPT fitting on top of the cover next to the magnetic fill plug for you to install a temperature sensor. And just like the other Mag-Hytec differential covers, it uses a rubber O-ring seal that is cast into the mating surface of the cover. The fluid capacity is increased from the stock cover's 7.6 pints to 14 pints.

We call this this AAGC for American Axle Gear Cover.

Differential Cover for 2003 Ram 3500
May 27, 2018  |  By tim tanker
Mag-Hytec provides extremely high quality products. I purchased this cover along with a trans pan and could not be happier with my purchases. This cover fits and seals beautifully on my '03 Ram 3500 dually. It is super easy to monitor the fluid level with the large sight window located on the back of the pan. You don't even need to get under the truck to check your lever-very convenient! My diff took 5.3 quarts of Lucas 75W-140 to reach the midway mark on the sight window. This is less than the fluid volume that is shown by the manufacturer.
