ICON dual-rate coil spring kit for 2003–2012 Ram HD 4WD offers 4.5" of front lift with a two-stage spring rate tuned for ride quality and compression control. The dual-rate design provides a compliant initial ride and a stiffer secondary rate under load to resist bottoming. These springs are intended as part of a lift conversion to improve ground clearance and maintain usable on- and off-road performance.
