Fabtech K2282DL 6″ Radius Arm System With Dirt Logic Shocks

Designed for the 2017 Ford F450/F550 4WD, Fabtech’s 6-inch Radius Arm suspension system is engineered to handle the extreme on-road and off-road demands of heavy-duty Super Duty trucks. The F450 and F550 feature a more robust suspension than the F250 and F350, requiring specialized components developed exclusively by Fabtech.

This Radius Arm system is a complete upgrade to the factory suspension and delivers increased strength and durability for use with oversized tires. The design has been proven through more than 10 years of service in consumer, commercial, and military applications, demonstrating long-term reliability in demanding conditions.

Fabtech’s precision suspension geometry and high-quality components set this system apart from other radius arm designs. Each component is engineered to work together to improve ride quality, steering control, and overall suspension performance while maintaining proper driveline and steering angles.

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
