Fabtech suspension lift kit.
The near stock track width keeps the tires under the fenders for a clean appearance. Fabtech's proprietary steering knuckle geometry provides excellent lock to lock turning radius to maneuver in tight spots. Triple front diff mounts reposition the differential for vibration free operation at high speed. They are designed for aggressive offroad use yet have a supple on road feel. Rear Dirt Logic 2.25 shocks aid in damping the vehicle for a balanced ride. Fabtech has addressed all aspects of the Trail Boss suspension for full suspension travel with lock to lock steering without over cycling.
A suspension lift raises ride height to clear larger tires; component kits vary in what they include, so check the parts list.
