The 2008–2016 Ford F350 4WD and 2011–2013 Ford F450 4WD (8 lug) can be upgraded with our advanced Radius Arm System designed to improve strength, steering stability and overall suspension performance.
Our patented radius arms feature a fully tubular structure reinforced with dimple-die side plates for exceptional durability. An adjustable alignment cam at the axle allows precise caster correction to maintain proper steering and handling after lifting.
The front spring lift is achieved using Fabtech coil springs, providing improved ride quality and consistent suspension performance. The system also includes a track bar relocation bracket, Pitman arm, sway bar drops and additional components to maintain correct steering geometry.
Rear lift is provided by a block and U-bolt kit, delivering reliable height increase, a stable stance and dependable load-carrying capability.
