In the megacab and crew cab 2500 with 6.4L and 6.7L front and rear axle ratings are 5500/6500, if you have a 5.7L it's 5250/6000. Ram has ratings from 5000/6000 thru 5500/6500 depending on the truck in the 2500 class that is ordered. I know that the diff has a 11-1/4 ring gear and the 3500 DRW have a 11-3/4 ring gear at least in 15 and 16.
Just some added info on 15/16 Ram 2500.

Actually coils in the rear started in 2014.
