The ICON coilover conversion suspension system is a great way to lift your 4WD 2017-2023 Ford F-250/F-350 Super Duty while improving ride quality and performance. This upgraded Stage 3 system is great for towing, rough construction site terrains, and country dirt roads all while keeping a smooth highway feel. ICON's Stage 3 System is comprised of 2.5 Series remote reservoir coilovers that are adjustable from 2.5-3” or 3.25-3.75 of front lift over stock (depending on year model and option package), adjustable front track bar with massive FK rod end, alignment cams for adding caster, rear leaf spring expansion packs with blocks and U-bolts for a more compliant ride and reduced axle wrap, nd ICON 2.5 Aluminum Series piggyback reservoir rear shocks. ICON 2.5 Series remote and piggyback reservoirs 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.
