The ICON Vehicle Dynamics Ford 2023-2025 F-250 and F-350 Super Duty 4WD Radius Arm System is designed with adjustable caster cams allowing fine tuning of caster angle for optimum drivability. Their added caster allows for use with 2-6” of front lift over stock with the radius arm installed in the factory pivot, eliminating the need for caster bushings or radius arm drop brackets. 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. For trucks equipped with OnBoard Scales ICON also offers sensor linkage brackets for specific height ranges that allows attachment of the OE sensor linkages to the ICON radius arm, ensuring proper function of that system..
