ICON 99-07 Ford Super Duty 5"-8" Lift Rear Leaf Spring Kit

These Rear Springs are Progressively Rated to give your Super Duty a much better ride quality as well as on and offroad performance. The ten leaf construction makes sure the truck will ride smooth and ensures less spring fatigue to minimize sagging. The bottom three leaves of the packs are flat to provide the secondary rate to prevent harsh bottom outs and a smooth transition through the suspension cycle.
