I've heard mixed reviews on leveling. I originally wanted it..then heard the Jeep would not ride correctly if you just leveled it. the RR is a lift on all 4 corners, I did mine with Bilstien shocks in the rear and am very happy with it. I could fit the 265 Revo's without spacers. you'll still maintain the front "rake" on the Jeep to keep the stock handling and ride.
