Fabtech’s Radius Arm lift kit is engineered for the Ford Super Duty to handle demanding on- and off-road conditions. This heavy-duty suspension upgrade increases strength and durability while maintaining a compliant, comfortable ride for daily driving.
The system centers on Fabtech’s tubular Radius Arms, a design born from off-road racing experience to deliver superior rigidity without sacrificing ride quality. The front suspension includes Fabtech replacement coil springs tuned for balanced on- and off-road performance. Redesigned arms feature a new side plate and bold laser-cut logo for an aggressive, modern appearance.
*Compatibility and installation notes: Non-dually models only. Does not fit gasoline engines. Vehicles with a two-piece driveshaft may require additional driveshaft components. Vehicles equipped with the factory rear sway bar may require extended sway bar links for proper fitment.
