So I'd like to replace the coil springs and shocks on a 97 TJ I recently purchased. It was previously lifted and I was measuring the coil springs to match the current lift. As I understand it the stock height of loaded springs is 12 inches front, 8 inches rear. I have 16 inches in front, indicating a 4 inch lift??? My issue is measuring the rear springs. The top spring bucket is angled front to back. Do I measure front (shortest), center or rear (longest) length? I've read that some install 4 inch front and 2.5 inch rear lifts to level stock height. I just want to make sure I match the existing lift as the jeep runs well and looks great at current height. Any suggestions on confirming rear spring height?
