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!
