Fabtech’s Radius Arm lift kit is engineered for Ford Super Duty trucks to meet both on- and off-road demands. This heavy-duty suspension upgrade strengthens the factory suspension while delivering a smooth, compliant ride for daily driving and rugged terrain.
The system centers on Fabtech’s tubular radius arms, a design informed by offroad racing to provide superior strength and controlled articulation. The front suspension includes replacement coil springs tuned for improved ride quality on and off the road. Redesigned radius arms incorporate updated side plates and a bold laser-cut logo for a modern, aggressive appearance.

Vehicles with a two-piece driveshaft may require additional drivetrain modification. Vehicles equipped with a factory rear sway bar may require extended sway bar links or related hardware to maintain proper geometry. Professional installation and alignment are recommended.
