Find a friend with a similar year 3500 (with leaf springs). Drive it a few miles. After that, you’ll think that 2500 is a Cadillac.....

I ended up putting Bilsteins on my 3500. It did help (some). I didn’t have good luck with Cooper ST maxx’s. They were worn out at 30k. The Falken AT3’s I’ve got now seem to be doing much better (and are smoother/quieter).....
