OVERVIEW
ITEM# ICF311
MFG# K62522L
The 2020-2023 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 2020-2023 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 ICON's Super Duty systems are known for.

The ICON 2.5” suspension system is a great way to lift your 4WD 2020-2023 Ford F-250/F-350 Super Duty while improving ride quality and performance. This upgraded Stage 2 system is great for towing, rough construction site terrains, and country dirt roads all while keeping a smooth highway feel. ICON's Stage 2 System is comprised of dual rate coil springs, 2.5 Aluminum Series piggyback reservoir front and rear shocks, alignment cams for adding caster, and rear leaf spring expansion packs with blocks and U-bolts for a more compliant ride and reduced axle wrap. ICON 2.5" piggyback reservoir shocks ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. With the endless hours ICON has spent testing and tuning ICON's suspension components and shocks as a complete package, you can rest assured you have the best suspension solution on the market.
