Designed for 2017-2022 Ford F250 and F350 4WD trucks, Fabtech’s 4" Radius Arm Lift Kit is built to meet the demanding on-road and off-road needs of Super Duty enthusiasts. This heavy-duty suspension upgrade enhances overall strength and durability while delivering improved ride quality and control compared to the factory suspension.
The foundation of this high-quality lift kit is Fabtech’s legendary tubular radius arms, developed from years of off-road racing experience. The tubular construction provides exceptional strength while allowing smooth suspension movement, resulting in a comfortable and compliant driving experience. This design allows the truck to confidently handle rugged off-road terrain while maintaining stable and predictable manners during everyday driving.
The front suspension is equipped with Fabtech replacement coil springs engineered to deliver consistent lift height and a smooth ride both on and off the road. The redesigned radius arms feature updated side plates and a bold laser-cut Fabtech logo, giving the system a modern, aggressive appearance that stands out while providing proven performance.
