Beyond the added ground clearance, the dual rate design of ICON springs provides a softer initial rate for superb on-road comfort and a firmer secondary rate that delivers excellent bottoming resistance and superior off-road performance.
The ICON Vehicle Dynamics 2020-UP Ford F-250 & F-350 Super Duty 4.5" coil springs are designed for drivers demanding the ultimate in performance and ride quality, while allowing for increased wheel travel (when used with ICON shocks) and the fitment of larger tires.
