The Fabtech Radius Arm lift kit is a heavy-duty suspension upgrade engineered for the Ford Super Duty to handle demanding on- and off-road use. This system adds strength and durability to the factory suspension while maintaining a comfortable, compliant ride for everyday driving.
The kit centers on Fabtech’s tubular radius arms, designed from offroad racing experience to deliver superior strength and controlled articulation. The front suspension includes replacement coil springs tuned for improved ride quality on and off pavement. Redesigned radius arms feature a new side plate and a bold laser-cut logo for a modern, aggressive appearance.
*Compatibility and installation notes: Non-dually models only. Not compatible with gasoline engines. Vehicles equipped with a two-piece driveshaft require an additional driveshaft component. Vehicles with a factory rear sway bar require extended sway bar links for proper installation.
