Designed for 2017-2022 Ford F250 and F350 4WD trucks, Fabtech’s 4" Radius Arm Lift Kit is engineered to handle the demanding on-road and off-road needs of Super Duty enthusiasts. This heavy-duty suspension upgrade strengthens the factory system while delivering improved ride quality, stability, and control.
At the core of this premium lift kit are Fabtech’s legendary tubular radius arms, developed through decades of off-road racing experience. The tubular construction provides exceptional strength while allowing smooth suspension movement for a compliant, comfortable driving experience. This balanced design enables the truck to confidently tackle rugged off-road terrain while maintaining predictable handling for daily driving.
The front suspension is equipped with Fabtech replacement coil springs engineered to provide consistent lift height and excellent ride quality both on and off the road. The redesigned radius arms feature reinforced side plates and a bold laser-cut Fabtech logo, giving the system a modern, aggressive appearance that stands out while delivering proven performance.
