Kelderman Manufacturing has designed a front four-link air-ride conversion kit for the Ford F-650 and F-750. The company says the easy-to-install system greatly improves ride comfort, decreases shock and fatigue, and improves the overall look of the truck – giving it a more leveled look in the front.

Kelderman’s kit comes with a heavy-duty front sway bar kit, height control valve that ties into the factory air supply, heavy-duty Firestone air bags, and all necessary brackets and hardware. When carrying a heavy load, the automatic height control valve is designed to compensate for the added weight to level the truck.

Kelderman says its system, developed with top-grade components, replaces the factory-built leaf springs with a quality-engineered four-link suspension that is maintenance-free and bolts easily into existing holes. For more information, go to
