The 2008–2016 Ford F250/F350 4WD and 2011–2013 Ford F450 4WD (8 lug) can be upgraded with our advanced Radius Arm System designed to improve suspension strength, steering stability, and overall ride 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 ensure proper steering control after lifting.
The front spring lift is achieved using Fabtech coil springs, delivering improved ride quality and consistent suspension performance. Completing the system are a track bar relocation bracket, Pitman arm, sway bar drops and additional components that maintain correct steering and suspension geometry.
Rear lift is provided by replacement leaf springs and a U-bolt kit, ensuring a stable stance and dependable load-carrying capability.
