The Fabtech 6" Radius Arm lift kit is a heavy-duty suspension upgrade engineered for Ford Super Duty trucks. Designed to handle demanding off-road terrain while maintaining a smooth, compliant ride on pavement, this system adds strength and capability to your vehicle's front and rear suspension.
At the core of the kit are Fabtech’s tubular Radius Arms, built from a performance-driven design that blends off-road racing durability with everyday driving comfort. The front suspension includes Fabtech replacement coil springs tuned to preserve ride quality both on- and off-road. Redesigned radius arms feature a new side plate and a bold laser-cut logo for a modern, aggressive appearance.
Benefits: Increased suspension strength, improved off-road capability, maintained ride comfort, and a distinctive, aggressive look.
