Fabtech?s world renowned IFS suspension design for the GM 1500 provides excellent drive ability both on and offroad. There is zero bump steer throughout the suspension cycle that helps reduce drive 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 excellent lock to lock turning radius to maneuver in tight spots. Heavy duty 1/4" thick steel crossmembers feature OE style alignment cam pins that utilize the factory 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 steer while achieving 6? of lift. Rear lift is accomplished with a 5" Block and u-bolt system. Includes rear Performance Shocks. Fabtech has addressed all aspects of the suspension for proper wheel travel and lock to lock steering without over cycling. Comes with a free 5 year 60,000 mile Powertrain Warranty.
