[goducks10]

Interesting article that breaks down the real difference between current 3/4 ton and 1 ton trucks.

Shiner, is there any physical difference to the front axle on a gasser vs a diesel to account for that difference in rating? Are the springs slightly stiffer or something? I've never noticed that there was a difference...

I thought the 6.4 2500s were the same 6000/6500, at least those with the 18" or 20" tires (which has to be about all of them). I could be mistaken, though. I think the only difference is heavier springs on the diesels to deal with the extra weight.

I looked at the spec sheet in 2014 when I bought mine, the 4x4 2500/3500 6.4L had a 5,500 front GAWR and the 4x4 2500/3500 diesels had a 6,000 front GAWR.

The axles are the same. As far as the front coils, I don't know the actual specs, but I do know there are at least 8 different part numbers on Mopar parts online. I which Ram would go into more detail in their body builder like Ford does in their spec sheets.

Most of that weight goes to the front axle. Unless you are hauling a truck camper the difference is irrelevant.

I see it posted often in the truck camper section about someone buying a gasser instead of diesel to get more payload, yet the rear weighs the same on both configurations of the same truck, so the payload difference is due to the limit on GVWR in that Class of truck and not due to capacity.

My F250 came with the standard 17" wheels that were rated lower than the optional 18" - The F350 of that era came with the higher rated 18's as stock. I was able to buy a new set of dealer take-off mounted 18's for less than just replacing my 17" tires, so I now owned a F250 with OEM optional suspension and tires that was identical to a F350 except for the badging and 2" lower rear axle block. In current models, there is more is more difference between the two Ford trucks but not really that much.

"So again, the only difference between the 2500 and 3500 is the rear suspension."

That is what carries MOST of the weight. With my hitch full forward and full RAWR I add under 200# to the front axle.

My apologies. I generally try to use correct terms when I talk. You chose another route. Kudos for innovation...

The few Rams I saw on lots when I was shopping that had the 5.7 also had 17" wheels and tires that were rated lower than the 18"/20" combos on all of the 6.4/Cummins trucks.

So it's not the engine holding it back. Upgrade to the bigger wheels and you should get the same payload...or can't you get the bigger wheels with the 5.7?

Would have been nice if they put it in tabular form.

Obviously, the duallies are a different ballgame but other than the Dodge, it looks like it's mostly the rear suspension still.

To clarify... Dodge doesn't make the trucks anymore, its a Ram.

Also, the difference in the 6.7 Ram 2500 and 3500 is also just the rear suspension. The rear coils in the 2500 are rated exactly 500 lbs less than the the rear leaf suspension of the 3500.

Technically the 6.4 has a different transmission then the 6.7... but everything else is identical to the 6.7 configurations. So again, the only difference between the 2500 and 3500 is the rear suspension.

What I don't get is how Ram has a higher GVWR/payload for the 6.4 Hemi vs 5.7.

Makes no sense why a bigger engine can CARRY more. They both have enough raw power to tow way more than their payload.

To get people to purchase the higher profit margin engine.

Torque and cooling

The Cummins have the lowest payload of them all...

I ask because DOT scales here do enforce GVWR. They don't care how much you tow (as that's a powertrain warranty spec).

Seems stupid the weight capacity is held back by a lower spec powertrain. I agree profit margins is all I can think of.

The GVWR your truck is registered and paid for or the GVWR from the sticker that is on your door? These can be two different numbers. I have never heard of cops being able to enforce the manufacturers GVWR. I have heard of them enforcing registered GVWR.
