What is the actual difference between the Ram 2500 and 3500 single wheel pickups besides leaf springs and coil. Are the bearings and brakes the same if both have 18 inch rims?
In the old days (not that long ago really) for most of the manufacturers, the difference between a 3/4 ton and a SRW 1 ton was the spring pack.
Dodge did make a pretty big change when they went with coil springs in the 3/4 ton. That's a fundamental change in suspension design...not sure exactly what else changed but just swapping out springs to make a fake 1 ton is likely not as simple.
