8" 4LINK SYS W/COILS & DL RESI SHKS 17-21 FORD F250/F350 4WD DIESEL.

Fabtech's 8in 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 8in 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 4in longer than stock and is offset to the driver side with a stout 1/4in thick steel mounting bracket. This design helps keep the Track Bar and Draglink closer to parallel than the factory angles to reduce push in
