Ram 2500 rough ride question
I own a 2018 RAM 2500 CTD and I have a question about the rough ride. I've had quite a few 1/2 ton trucks but this is my first 2500. When I first purchased the truck I noticed a shimmy when driving on...

Leaf springs don't move (bend) as much as coils through their spring/load curve. Varied spring rate is through a combo of leaf thickness/length/width/taper/numbers in the stack/etc
Straight torsion bars don't twist as much as coils through their spring/load curve. They can be tapered, bit that greatly increases their cost...and...at such a short length, a potential stress raiser(s) at the rolled transition (s)
Coils are just torsion bars wound into a coil and twist much more than straight torsion bars
Add in varied pitch on those coils and you have variable spring rates per distance compressed
Locomotives have suspenion coil springs abd an average locomotive engine weighs in aroind 500,000 lbs
Automotive coil springs can be designed to have very soft rates in the initial compression travel...to the have very high rates as the compression continues...but...coil spring can NOT locate the live axle like a leaf setup can...so hard links are the norm...and they can reduce the rude quality
IMHO...these are trucks...unless towing with a CUV or Car...still ride quality isn't on my have to have list and is towards the bottom of my nice to have list
