The ICON Vehicle Dynamics Ford 2005-2022 F-250, F-350, and F-450 Super Duty Radius Arm System is designed with adjustable caster cams for use with stock height trucks up to 3” of front lift with the radius arm installed in the factory pivot. When used in conjunction with an ICON radius arm drop bracket system, proper caster can also be maintained for 4” to 7" lifts, including coilover conversion systems. They feature a sealed pivot bushing that minimizes road feedback and ensures a long life and quiet operation. Additionally, their fabricated, fully boxed design ensures strength and utilizes a profile optimized for tire clearance at full steering lock, making a 37” tall tire clear without coming in contact with the radius arm.
