Designed for the 2017-2022 Ford F250/F350 4WD, Fabtech’s 6-inch Radius Arm lift kit is engineered to handle demanding on-road and off-road use. This heavy-duty system is a complete upgrade to the factory suspension, delivering increased strength, durability, and confidence for the Super Duty platform.
At the core of this system are Fabtech’s legendary tubular radius arms. Developed from extensive off-road racing experience, the tubular design provides exceptional strength while maintaining a smooth, compliant ride for everyday driving. This balance allows the vehicle to confidently handle rugged terrain while remaining comfortable on the street.
The front suspension is equipped with Fabtech replacement coil springs that are specifically tuned for excellent ride quality both on and off road. The redesigned radius arms feature updated side plates and a bold laser-cut logo, giving the suspension a modern and aggressive appearance.
Included with this system are Dirt Logic 2.25 stainless steel reservoir shocks in the front and non-reservoir shocks in the rear. These shocks are ride tuned to work with Fabtech coil springs and oversized tires, delivering excellent ride quality, control, and stability in all driving conditions.
