This Rough Country 1157 Body Lift for the Jeep Wrangler TJ provides a full 1.25" of additional tire clearance, as opposed to the standard 1" provided by most other manufacturers. The 1.25" spacers nest with the factory body mounts keeping the body properly aligned with the frame. This design provides lift while retaining the noise and vibration canceling characteristics of the factory mounts. The new shifter adapter allows you to run any 1" or 1.25" body lift on a TJ with a manual transmission without having to cut the inner shift boot. It also gives you back the lost shifter length due to the body being raised away from the frame.
