I have a 1998 chevy tahoe 4dr 4wd 5.7L. I have a 4 inch pro comp lift, New 315/75/r16 nitto terra grapplers a/t, upgraded from es 3000 shocks to es 9000. I believe my torsion bars are worn out because i can push on the front bumper and move the truck up and down atleast 12 inches or more. It greatly affects the way it handles.I am looking for a much stiffer ride and I have been looking for a heavier duty torsion bar but have had no luck, Any infromation would be greatly appreciated thanks.
