overview
The ICON 2.5” suspension system is a great way to lift your 4WD 2023-2024 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 dual rate coil springs optimized for trucks equipped with diesel engines, 2.5 Aluminum Series piggyback reservoir front and 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" 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.
