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.
