Fabtech’s 6″ Radius Arm lift kit for the 2017-21 Ford F250/F350 4WD (Gas) is engineered to meet the on-road and off-road demands of Super Duty truck enthusiasts. This system serves as a heavy-duty upgrade to the factory suspension, offering increased strength and durability for a wide range of driving conditions.
At the core of this high-quality lift kit are Fabtech’s legendary tubular Radius Arms. Their tubular structure combines Fabtech’s extensive off-road racing heritage with engineering aimed at delivering a smooth, compliant driving experience. The result is a suspension system with exceptional strength—capable of handling rugged off-road terrain while still providing everyday driving comfort.
The front suspension is equipped with Fabtech’s replacement coil springs, specifically developed to deliver outstanding ride quality both on and off the pavement. The redesigned Radius Arms also feature a new side plate and bold laser-cut logo, giving the vehicle a modern, aggressive look that stands out whether you're tackling trails or city streets.
