I know bags technically donโt add capacity. BUT as an example my 15 RAM only has two thin full leaf springs with two short ones to control axle wrap. My rear axle weight is at least 9,750# with 6k pin. Truck is rock solid.
So take it for what itโs worth!
2000-2002 itโs easy to upgrade to 2003-2009 3rd gen front brakes. Insane braking difference!!!

Let's see.....
We'll comply with the rear axle rating. The axle manufacturer knows what they are doing.
Well Dana the axle manufacture rated the Dana 80 at around 10,000#
We'll comply with the tire loading specs, those guys have their act together.
I believe the tires on a 2001 Ram DRW were 17" rated at 3,042# each so 12,168# of tire capacity.
We'll comply with the GVWR, Dodge knows what they are doing.
Well the 2001 Ram 3500 DRW had a GVWR of 11,500#, so should be within that spec.
The gross combined vehicle rating is idiocy and we will just ignore that one.
This is a power and gear ratio rating, comfort of towing.
Who decides which ratings to ignore and which to follow? Does chipping an engine improve the cooling capacity, shock damping, frame strength or any of a number of other factors Dodge considered when designing the truck and assigning capacity numbers? I choose to stay within the factory specs.

The Cummins will have no issues towing that kind of weight however the weak link is the 47RE auto tranny. The 47RE can be rebuilt to stand up to heavy towing duties. Now if the tranny is the 5 speed manual NV4500 or the 6 speed manual NV5600 then no problems.
You have the truck so like all truckers drop by a set of scales and get the trucks front and rear separate empty axle weights. That way you know how much payload the truck can carry.
On my 2001 all the door tag had was GVWR....FAWR...RAWR numbers. No payload numbers on the older trucks....eliminates confusion.

Durb wrote:Yeah, I kind of agree with most of what you're saying, but I just don't think it's as black and white. If you increase the HP and change the gear ratio, can you pull more load than what the GVCWR says you can? If not, why not?
That truck with a 3.55 rear axle has a gross combined weight rating of 20,000#, with a 4.10 axle 21,000#. The empty truck weighs 6,700# if 2WD, 7,000# if 4WD. Toss in a couple of passengers and a hitch, maybe 700#. This leaves you with an "in spec" trailer weight of 12,300# to 13,600#. The truck may do it but I think it would be poor advice to tell you to go for it. You will see a bunch of anecdotal advice telling you otherwise and contrary to the manufacturer's numbers.

You probably don't have the rear axle capacity to carry that pin weight, even with a dually (2001).
The engine will handle it fine. Maybe not at 70mph, but at any reasonable speed.
