The ICON 2.5" dual‑rate spring kit levels and enhances ride quality for 2003–2012 Ram 2500/3500 HD 4WD trucks while providing a 2.5" lift. The dual‑rate design delivers a softer initial ride zone for comfort and a firmer secondary rate to resist bottoming during heavy use. ICON springs are shot‑peened, pre‑set to prevent sagging and finished with a dual‑stage powder coat for corrosion resistance. The kit includes longer urethane bumpstops and sway bar drop brackets; front shocks matched to these springs are recommended for complete installation.
