These ICON 5" rear lift leaf springs for 2008–2016 Ford Super Duty trucks are progressively rated to improve ride quality and minimize spring fatigue under load. The multi-leaf design smooths suspension transitions and the flat bottom leaves provide a secondary overload rate to prevent harsh bottom-outs, delivering a smoother cycle through the suspension while replacing the OE rear springs.
