ICON Triple Rate Coil Spring Kit for the 2021–2024 Ford F-150 Raptor is engineered to improve suspension performance while maintaining ride quality under varying loads and driving conditions. Its triple-rate design delivers a balanced combination of comfort, support, and control by progressively adjusting spring resistance based on compression. The soft initial rate allows for increased suspension articulation and droop travel, the mid-range supports everyday driving stability, and the firmer final rate helps manage heavier loads and impacts without harsh bottoming out. These springs are built with a tapered wire profile and extended free height to ensure they remain seated through the full range of suspension movement. Designed to maintain the factory ride height of Gen 3 Raptors without added rear weight, this kit provides consistent rear suspension behavior whether unloaded or lightly equipped. The coil springs are finished with a corrosion-resistant coating and include a lifetime guarantee against sagging or structural failure.
