Overview
Designed to provide a height-adjustable option to the extremely popular ICON Vehicle Dynamics 4.5” Ford Super Duty Suspension Systems, these coilover conversions provide excellent on-road ride quality and off-road performance while at the same time allowing for end-user ride height adjustability.
This Stage 5 system sees the inclusion of the ICON Vehicle Dynamics Ford Super Duty Radius Arm System that 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.
