ICON Vehicle Dynamics 4.5" Stage 5 Suspension System with Radius Arms

Overview
The 2020-UP Ford Super Duty trucks sit at a lower ride height than 2017-2019 models, and although many of the 2017-2019 components will physically fit 2020 models, the resulting ride height is often taller than desired. So, engineers at ICON designed new progressive rate coil springs that achieve the correct advertised lift heights while still retaining the great ride quality, predictability, and performance that our Super Duty systems are known for.

This ICON Vehicle Dynamics 4.5” suspension system is a great way to lift your 4WD 2020-UP Ford F250/350 Super Duty while drastically improving ride quality and performance. The Stage 5 system is perfect for on-road and off-road use including towing, job site duty and hardcore off-road adventure. ICON's Stage 5 System is comprised of dual rate coil springs, adjustable track bar, 5" block kit, ICON CDC Valve 2.5 Aluminum Series front and rear piggyback reservoir shocks and dual opposing 2.0 Aluminum Series steering stabilizer kit for the ultimate in on-road comfort and off-road performance.

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.
