the coil springs are gettin old an weak on my 97 TJ, especially the right rear. it droops real bad when i let the clutch out, i know my 4 banger is a torque monster beast:flipoff2: but that shouldnt happen. prob is my lift kit is ancient and it was on there when i bought it, and the former owner didnt install it either so hes no help. can i just put a 4" lift spring in and forget about it or do i need to measure the lower control arm length or somethin? its either a 3.5 or 4" lift, i think. all the parts used to be red (now rust) and the kit only had front lca, tcase drop, track bar brackets. any ideas?
