Fabtech’s 4" Radius Arm lift kit for the 2017-21 Ford F250/F350 4WD (Gas) is engineered to meet the demands of both on-road and off-road driving for truck enthusiasts. This system serves as a heavy-duty upgrade to the factory suspension, delivering added strength and improved performance.
At the core of this high-quality lift kit are Fabtech’s legendary tubular Radius Arms. Their tubular design reflects extensive offroad racing experience and a commitment to providing a smooth, compliant driving experience. The result is a suspension system with exceptional strength that performs confidently over rugged terrain, yet still handles everyday driving with ease.
The front suspension is equipped with Fabtech’s replacement coil springs, designed to deliver a comfortable ride both on and off road. The redesigned Radius Arms feature a new side plate and bold laser-cut logo, giving them a modern, aggressive appearance that stands out whether you're navigating trails or town roads.
