Fabtech 17-20 Ford F250/350 4WD Diesel 8in 4 Link System w/Stealth Shocks

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. 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.
