ICON 5" rear lift leaf springs for 1999–2007 Ford F-250/F-350 Super Duty are progressively rated to improve ride quality and payload control. Multi-leaf construction minimizes spring fatigue under load and the flat bottom leaves provide a secondary overload rate to prevent harsh bottoming. Replaceable bonded bushings, galvanized separators, and direct bolt-in fitment support simple installation and durable, quieter operation.
