Designed for 2017-2022 Ford F250 and F350 4WD models, Fabtech’s Radius Arm lift kit is engineered to meet the demanding on-road and off-road needs of Super Duty truck enthusiasts. This system is a heavy-duty upgrade to the factory suspension, providing increased strength, improved stance, and reliable performance.
At the core of this high-quality suspension system are Fabtech’s legendary tubular radius arms. The tubular construction is the result of Fabtech’s extensive off-road racing experience combined with a commitment to delivering a smooth, compliant driving experience. This design results in a suspension system that offers superior strength for rugged off-road terrain while remaining comfortable and predictable for everyday driving.
The front suspension is equipped with Fabtech replacement coil springs that have been specifically developed to deliver excellent ride quality both on-road and off-road. These springs enhance suspension performance while maintaining drivability for daily use.
The redesigned radius arms feature a new side plate design with a bold laser-cut Fabtech logo, giving the suspension system a modern and aggressive appearance that stands out on the street and on the trail.
This complete suspension package provides enhanced durability, performance, and visual appeal, making it an excellent upgrade for Super Duty owners seeking strength and capability without sacrificing ride comfort.
