I had Eaton Detroit put together new spring stacks for the rear of my 1.5 ton because of two issues.
1. Super bouncy, harsh, hard ride. I had them cut the rate in half, from 4000 to 2000 pounds and dropped the ride height by 2" (it sat that much higher in back).
2. New pins, U-bolts and bushings all around (after nearly seventy years, they were predictably tired & worn).
NOTE...I am also adding shocks (which it never had in back) to help smooth things out.
