Icon dual rate 2.5" lift coils for 2005-15 Ford F-250/350 Superduties. The softer initial rate makes for a great street ride and the firmer secondary soaks up offroad driving. Kit includes alignment cams to keep your front castor correct. If you install a kit without adjust for castor, poor driving and handling characteristics will result.
These coils are designed to sit level with a 3.5" rear block. We have those available along with any other suspension accessory you may desire!
