Icon 17-19 Ford F250/f350 4wd, 2.5" Lift, Stage 4 Suspension Sys W/ Leaf Spring

The ICON 2.5” suspension system is a great way to lift your 4WD 2017-2019 Ford F-250/F-350 Super Duty while improving ride quality and performance. This upgraded Stage 4 system is great for towing, rough construction site terrains, and country dirt roads all while keeping a smooth highway feel. Also included in this stage is ICON's CDC Valve front and rear shocks, for those desiring an easy way to tune the ride externally with 10 settings, from soft to hard. ICON's Stage 4 System is comprised of dual rate coil springs, 2.5 Aluminum Series CDCV remote reservoir front and CDCV piggyback reservoir rear shocks, adjustable front track bar with massive FK rod end, 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" remote reservoir and 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 our suspension components and shocks as a complete package, you can rest assured you have the best suspension solution on the market.
