The 2011–2016 Ford F350 4WD and 2011–2013 Ford F450 4WD (8-lug) can be upgraded with our advanced Radius Arm System, engineered for improved strength, handling, and suspension performance.
Our patented radius arms are built with a fully tubular structure and reinforced using dimple-die side plates for maximum durability. An adjustable alignment cam at the axle allows precise caster tuning, ensuring proper steering control after lifting.
The front lift is achieved through Dirt Logic 4.0 coilovers, delivering exceptional damping performance, increased wheel travel, and enhanced ride quality. Completing the front suspension system are a track bar relocation bracket, Pitman arm, sway bar drop brackets, and additional components designed to maintain correct steering and suspension geometry.
Rear lift is provided by a block and U-bolt kit, offering reliable height increase and a balanced stance while maintaining load-carrying capability.
