Actual manufacturer RAWR has my curiosity for some reason..In your case not knowing the specifics of your 2002 2500 Dodge,you either have a Dana 70 (7500 RAWR) or the Dana 80 (11,000 GAWR)..Derated by Dodge to the weakest link(tires etc)..
They put the Dana 80 (11000#) in "1994-2002 2500 equipped with manual transmissions and Diesel or V10 engines"..So if that is what you have,your good to go on the rear axle, with all your upgrades...
If you have the Dana 70 then your probably maxed out(7500#) or slightly over with an Arctic Fox 811 and any tongue weight from a trailer would put you even more over the RAWR..
The Dana 70 HD is rated at 10K I believe if that is somehow what you have..
JMHO
