The ICON Vehicle Dynamics Ford 2023-2024 F-250 and F-350 Super Duty 4WD 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, eliminating the need for caster bushings. For taller lift heights from 4-5.5" of front lift, these radius arms can be installed in the factory pivots along with caster bushings to elimiate the need for radius arm drop brackets and improve ground clearance.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.
