Fabtech’s world renowned IFS suspension design for the GM 3500HD 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 driveability 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 eccentric style alignment cams for easy adjustment. Triple front diff mounts reposition the differential for vibration free operation at high speed.

Fabtech offers their top of the line Dirt Logic 2.25 shocks with this 3500HD lift kit. They are constructed with a stainless steel body and a NitroSteel® piston rod for maximum corrosion resistance and durability. These high quality Dirt Logic shocks will provide a superior ride quality both on and offroad with excellent damping for offroad use.

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.
