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 system is a heavy-duty upgrade over the factory suspension, delivering increased strength, improved control, and enhanced ride quality for trucks that work hard and play harder.
At the core of this premium lift kit are Fabtech’s legendary tubular radius arms, developed from decades of off-road racing experience. The tubular construction provides exceptional strength while allowing smooth suspension movement for a compliant and controlled driving experience. This balanced design allows the truck to confidently tackle rugged off-road terrain while maintaining comfortable, predictable handling during daily driving.
The front suspension is equipped with Fabtech replacement coil springs specifically engineered to provide consistent lift height and improved ride quality both on and off the road. The redesigned radius arms feature updated side plates and a bold laser-cut Fabtech logo, giving the suspension a modern, aggressive appearance that stands out while delivering proven performance.
