ICON 23 Ford F250/350 Front 2.5in. Diesel Dual Rate Spring Kit

The ICON Vehicle Dynamics 2023 Ford F-250 and F-350 Super Duty 2.5" 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. The ICON Ford Super Duty coil springs provide 2.5" of lift height and feature a dual rate design optimized for use with trucks equipped with diesel engines. The dual rate design 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. Caster correction cams are also included to ensure proper caster angle with the new, taller ride height. Like all ICON coil springs, they feature a lifetime guarantee against sagging/breakage to produce confidence in knowing that you have the best suspension products available for the 2023 Ford Super Duty.

Additional Information

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.
