Dodge Ram Springs

I am looking to change the springs on my 99 2500 4X4 Diesel to make it capable of carrying more weight. I have heard that the drive train is the same on the 2500 and 3500, and the only difference is the leaf springs. Does anyone know if this is true ? I am thinking of purchasing a camper that currently exheeds the weight of my trucks specs. Thanks.

have you thought about air bags for your suspension?

I think the only diffiernce is that the 3500 axles were all dual rear wheel, and the 2500 are single rear wheel. I'll see if I can find more information to confirm that. it may not hurt to check with a dealership just to make sure. it would be pointless to upgrade the springs if the axle can't handle the weight.
if the axle is the same, then you have lots of options, all together new springs, add on overloads, air bag overloads

ok, I did some checking, the axles are diffirent between the 2500 and 3500, the 3500 axles have a higher weight rating. I guess it depends on how much the camper is over you GVW rating. you can add some type of helper or overload spring, but you would still be overloading the axle, and may experience accelerated wheel bearing wear or other axle related problems.

You should think twice before you overload the GVW-rating of your truck. I'm certain you have the technical skills to make it happen. Here's where you may get bitten - insurance and liability. Should you get involved in a motor-vehicle accident; regardless of fault - your insurance company and certainly a 3rd party insurer will do its best to deny any claim you make and may try to stick you with damages by claiming you were at fault on the grounds of contributory negligence.

Do a 'below the radar' Q&A with your insurer, your MVA and if you have one an attorney - just to make sure you're not exposing yourself to unnecessary risk.
