ICON's 4.5" Stage 3 System is comprised of 4.5” lift coil springs optimized for trucks equipped with diesel 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 arms offer significantly more strength over the OE units and feature built in caster cams for on-vehicle caster adjustment, maintenance free bushings, and improved tire clearance at full steering lock, all while eliminating the need for drop brackets and thus raising ground clearance under the chassis. 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. ICON’s dual opposing steering stabilizer kit featuring ICON 2.0 Aluminum Series shocks improves steering damping to better control undesirable steering feedback caused by larger tires. Heavy-duty fabricated 5" rear blocks and U-bolt kit lift the rear of the vehicle and are designed to withstand heavy towing/hauling duty as well as the stresses of aggressive off-road use. ICON 2.5 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 with improved performance compared to 2.0 Aluminum Series shocks. 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.
