ICON K64524 Stage 4 Suspension System 4.5" Ford F-250/F-350 20-22 4WD

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 4 system is perfect for on-road and off-road use including towing, job site duty and hardcore off-road adventure. ICON's Stage 4 System is comprised of dual rate coil springs, adjustable track bar, 5" block kit, and ICON CDC Valve 2.5 Aluminum Series front and rear piggyback reservoir shocks.

The Stage 4 system sees the inclusion of the ICON Vehicle Dynamics Ford Super Duty 4-Link kit, which further improves performance by eliminating suspension bind commonly experienced with factory radius arms during articulation. This “freeing up” of the front end and the ability of the 4-Link Kit to maintain positive caster through the range of travel equates to an unparalleled ride quality in all conditions. With the endless hours ICON has spent testing and tuning our suspension components and shocks as a complete package, you can rest assured knowing that you have the best suspension solution on the market.
