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.
