Re: rear bounce

Lynn, my '71 GMC has 4" springs, 1" lowering block, shock relocators, shocks, & adj. panhard.... all CPP. I think it feels bouncy in the rear at Interstate speed. Particularly on concrete overpasses with expansion joints. Usually has no weight in the bed. I wonder if it's due to a combination of spring rate and shock valving. The front has 2.5" dropped spindles w/1 coil cut. The bounce bothered me worse a couple of years ago when I first changed the parts but I think i got used to it. Feels better now.
