Fabtech's world-renowned IFS suspension design for the Ford F150 provides excellent drive ability both on and off-road. There is zero bump steer throughout the suspension cycle that helps reduce driver fatigue while improving the overall drive ability of the vehicle. The near-stock track width keeps the tires under the fenders for a clean appearance. Fabtech's proprietary steering knuckle geometry provides an excellent lock to lock turning radius to maneuver in tight spots. Heavy-duty 1/4" thick steel crossmembers feature eccentric style alignment cams for easy adjustment. Triple front diff mounts reposition the differential for vibration-free operation at high speed. The factory coilover shocks are relocated from the bottom to allow for full steering while achieving 6" of lift. At the rear of the vehicle, the factory 2" block is replaced with a 5" Block and U-bolt system. Fabtech has addressed all aspects of the suspension for proper wheel travel and lock to lock steering without over cycling. For added confidence, this lift comes with a free 5-year 60,000-mile Powertrain Warranty.
