Fabtech’s 6″ Radius Arm lift kit for the 2017-21 Ford F250/F350 4WD (Gas) is engineered to meet the demanding on-road and off-road needs of Super Duty truck enthusiasts. This system delivers a heavy-duty upgrade to the factory suspension, providing increased strength, durability, and improved performance.
At the core of this premium lift system are Fabtech’s legendary tubular Radius Arms. Their tubular design blends Fabtech’s extensive off-road racing heritage with a commitment to delivering a smooth and compliant driving experience. The result is a suspension system with superior strength—capable of conquering challenging off-road terrain while still offering everyday comfort and maneuverability.
The front suspension features Fabtech’s replacement coil springs, carefully developed to ensure excellent ride quality on and off the pavement. The redesigned Radius Arms include a new side plate and bold laser-cut logo, giving the truck a modern, aggressive look that stands out whether you're navigating trails or city streets.
