I have a 97 K2500 ECSB with 454. This is a HD with the 9600 GVWR I believe. I just replaced the shocks with some KYBs gas-adjust and they ride better than the bilsteins did but the truck bounces like crazy. New ball joints and such. I loosened my torsion keys all the way and that helped. I'm wondering if its cause of the rear leafs being so strong. Any ideas?
