Fabtech K2289DL 4″ Radius Arm System With Front Dirt Logic 2.25 Resi Shocks & Rear Dirt Logic Shocks

Designed for the 2017-2022 Ford F250/F350 4WD, Fabtech’s 4-inch Radius Arm lift kit is engineered to handle demanding on-road and off-road use. This heavy-duty system is a complete upgrade to the factory suspension, delivering increased strength, durability, and improved performance for the Super Duty platform.

At the core of this system are Fabtech’s legendary tubular radius arms, developed from extensive off-road racing experience to provide superior strength while maintaining a smooth and compliant driving experience. The redesigned radius arms feature updated side plates and a bold laser-cut logo for a modern, aggressive appearance.

The front suspension utilizes Fabtech replacement coil springs that are tuned for excellent ride quality both on and off road. Included Dirt Logic 2.25 stainless steel reservoir shocks in the front and non-reservoir shocks in the rear are ride tuned to work with Fabtech coil springs and oversized tires for balanced performance and control.

This complete suspension system is designed to maintain proper steering geometry, improve wheel travel, and deliver confident handling whether navigating rough terrain or everyday driving conditions.

Our patented Radius Arms feature a full tubular structure strengthened by dimple die side plates with an adjustable alignment cam at the axle to allow caster adjustment. Front spring lift options includes 6 replacement
