My TJ is stock except for the 235/75x15 tires. Has 162,000 miles. The height at rear bumper is 16"; front bumper measures 18.5" from ground. Normal or in need of new coils, etc.
just for future reference.
stock rear coils on a 2000 TJ, are 8 inches from bottom perch to top of perch.
rear coils are 12 inches. This is where you can start, any lengths longer than this will show the amount of lift. I was happy to find this out, its a good knowledge baseline.
