ICON 2020+ Ford F250/F350 4.5in Stage 1 Suspension System

K64521 Overview
The 2020-2022 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.
The 4-link brackets, upper links, and lower links are sold separately, allowing the 4-link system to be customized for your specific Ford Super Duty year range.
