Coil suspension

So there is alot of talk about how much the ecodiesel can haul. Towing is around 9K which is plenty for me. I do not have a CDL and cannot tow above 10K anyhow. But hauling stuff in the back. my truck is 1300LBS. Family of 5 = 530lbs. So i can only haul about 800LBS.

My question is what is the weak point?? We have better towing power than the 5.7L. Even in the 2500. So its not the engine. i thought it was the rear suspension. Can we add better coils? maybe the 2500 ones? or is it the axles? Anyone with good knowledge of this stuff.. \

...here is the bottom line...

Your truck is not 1,300lb, 5,700lb maybe but not 1,300lb. The lightest ram is around 4,700lb the heaviest ram is 5,700lb.


The difference between our trucks and the 2500 is the springs, shocks, engine and transmission, tires also they used to have different axles but some forums are pointing out that the 2500 and the 1500 share the same axle. And cooling lots of cooling.

One of the main reasons our trucks are rated low on payload is because we are a Class 2a truck.
Truck classification - Wikipedia, the free encyclopedia

Taxes and requirements change the higher up the range you go. Our trucks are designed for light duty and underrated mostly because any higher and we are a 2500 and have to follow those rules and regulations.

So if you want to make a 1500 to do 2500 work you can, but you are no longer under warranty, and the price of modifications you might as well gotten yourself a 2500.

Now do they know you are going to run it hard yes, and they do allow for occasional use of stressing the truck...but under long term stress, your rear coils are going to sag, your transmission is going to need a tune up much sooner than norm, and if you dont up grade your cooling your are going to damage your components over time due to over heating.



Our trucks can take a overload of maybe a 1,000 pounds and shrug it off. Here is why

Payload is curb+passengers - GVCW+towing.

I think our trucks come with 500LB tongue weight limits with our truck (standard hitch?) but that can be added to a payload if not towing just know the bed of the truck is taking that much burden.

and lastly we are not the only trucks with this problem....all 1500s have this problem.

.....Its a half ton right?

Then yes its going to have the same problem...its a 1/2 ton problem.

And now that I think about it...I can see how going all aluminum body and saving 700 pounds can change a payload rating from 800lb to 1500lb.
Similar to a vehicle's gross vehicle weight rating, or GVWR, the gross combination weight rating is a specific maximum weight limit determined by the manufacturer. See rams tow rating website for how they do the calc.



It's important to remember that the GCWR is not an actual measurement of the weight of a tow vehicle and a trailer, but rather the combined maximum weight limit that the manufacturer has set for the two vehicles once attached.


used how rams website does the calc and they always seem to assume you are going to tow something.
