Fabtech 8-Inch 4-Link Suspension Lift Kit with Dirt Logic 4.0 Reservoir Coil-Overs and Dirt Logic Shocks (17-21 4WD 6.7L Powerstroke F-350 Super Duty SRW)Find parts that fit my vehicle

Description. Fabtech’s 8? 4 Link Conversion System for the Ford Super Duty is designed to provide maximum suspension performance for both on and offroad use. The system replaces the factory Radius Arm suspension with heavy duty 4 Link components for increased strength and functionality. The system will provide less caster change throughout the travel range which benefits on road driving. When offroad the 4 Link system will provide more articulation than a Radius Arm for increased terrain traversing at all speeds.

Unique to this 8? system is Fabtech’s extended length Track Bar to address the hyper sensitive steering box of the late model Super Duty. Fabtech is the only manufacturer with this exclusive system that offers proper steering performance. Fabtech’s extended length Track Bar is 4? longer than stock and is offset to the driver side with a stout 1/4? thick steel mounting bracket. This design helps keep the Track Bar and Draglink closer to parallel than the factory angles to reduce push in the steering. The Track Bar allows for full lock steering of 15.50 wide tires w/ 4-3/4? BS wheels.

Included in this system is the massive Dirt Logic 4.0 Resi Coilover Conversion for outstanding damping capacity offroad with a quality on road ride. The Coilover bolts in place of the factory coil spring without removal of the coil spring bucket. The giant 4? diameter aluminum remote reservoir mounts horizontally above the Coilover to allow for full compression travel with oversized tires. The Dirt Logic 4.0 Resi Coilover is the biggest and baddest on the market for the Ford Super Duty.

Fabtech’s 4 Link System has been proven in over 10 years of service in rugged commercial and military applications to ensure long life on your daily driven vehicle.

High quality components with properly designed suspension geometry makes this Super Duty system the pinnacle of all suspensions. Comes with a free 5 year 60,000 mile powertrain warranty.
