ICON's dual-rate coil spring kit for 2005+ Ford F-250 and F-350 Super Duty provides 4.5" of lift with a progressive rate for a softer initial ride and firmer secondary rate under compression. The design improves on- and off-road comfort, allows more wheel travel with ICON shocks, and supports larger tires. Springs include a lifetime guarantee against sagging or breakage and come as a complete bolt-on kit for the front.
