Product Details

This ICON Vehicle Dynamics 4.5” suspension system is a great way to lift your 4WD 2023 Ford F-250/F-350 Super Duty while drastically improving ride quality and performance and allowing fitment of larger, more aggressive wheel and tire combinations. This entry level system is perfect for on-road and towing use, as well as mild off-road use like job site duty and washboard gravel roads.ICON's 4.5" Stage 1 System is comprised of 4.5” lift coil springs optimized for trucks equipped with gasoline engines with a dual rate design that allows for a softer initial rate for superb on-road comfort and a firmer secondary rate that increases during compression for excellent bottoming resistance and off-road performance. Fabricated radius arm drop brackets correct suspension geometry and ensure proper wheel alignment with the OE radius arms. The fabricated track bar drop bracket allows the axle to be properly centered under the frame and reduces road feedback throughout the steering system with improved on- and off-road manners thanks to the elimination of bump steer. Leaf spring expansion packs provide 2" of rear lift over stock with improved ride quality and small bump compliance while also reducing axle wrap compared to lift blocks. ICON 2.0 Aluminum Series internal reservoir front and rear shocks feature a vehicle specific tune for improved vehicle handling and excellent ride quality on- and off-road. The included box kit includes fabricated front sway bar drop brackets to prevent bind, heavy-duty aluminum bump stop spacers, and high quality stainless steel extended brake lines.This suspension system features high quality CNC machined, laser cut, and brake formed components and with the endless hours ICON has spent testing and tuning our suspension components and shock absorbers as a complete system, you can rest assured you have the best suspension solution on the market.
