The ICON Vehicle Dynamics 2018-2023 Jeep Wrangler JL/2020-2023 Jeep Gladiator front 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 coil springs provide 2.5" of lift height on Wrangler JL (based on a factory equipped 4-door Rubicon) or 2" of front lift on Gladiator JT and feature a dual rate design. 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. 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 2018-2023 Jeep JL Wrangler or 2020-2023 Jeep Gladiator.
