I change my stock wheels and tires for some 20" IROC copies. I noticed the rear sat about an inch lower then the front. The jeep has 85000 miles on it. Changed to the Skyjacker 2.5 - 3 inch lift with the Skyjacker 2.5 lifted gas shocks. Looks and rides great.
I would recommend these to anyone look to bring your jeep back to life.
