2017-21 Ford F250/F350 4WD [Gas]

Fabtech’s 6" Radius Arm lift kit has been built for the Ford Super Duty to handle the on and offroad demands of the truck enthusiast. This system is a heavy duty upgrade to the factory suspension and will provide additional strength to the vehicle.

The heart of this high quality lift kit is Fabtech’s legendary tubular Radius Arms. The tubular structure design is the combination of our extensive offroad racing history and our desire to provide a smooth, compliant driving experience. The result is a suspension system with superior strength that can handle rugged offroad terrain and still navigate a grocery store parking lot with ease.

The front suspension receives Fabtech’s replacement coil springs that have been developed for a great ride on and off road.

The redesigned Radius Arms have a new side plate and bold laser cut logo that gives them a modern aggressive look that will turn heads as you tackle the toughest offroad terrain.
