Upgrade your 2017 to 2026 Ford Super Duty truck with the Kleinn spare tire train horn and onboard air kit, engineered specifically for owners who demand premium quality and precision vehicle-specific fitment. This premium heavy-duty package delivers the signature, earth-shaking blast of our high-performance acrylonitrile butadiene styrene plastic train horns paired with professional-grade pneumatic utility. We custom engineer chassis-specific, powder-coated steel brackets that bolt our genuine Kleinn components directly to existing factory holes under the vehicle, ensuring a true 100 percent bolt-on installation that requires absolutely no cutting, welding, or drilling. Providing the power for this system is a heavy-duty, 100 percent duty-cycle waterproof air compressor paired with a high-capacity air tank, creating a versatile onboard air station capable of inflating large tires, powering air tools, or operating air suspension bags. Every bracket, high-pressure line, and genuine component is precision-engineered to provide a factory-clean, stealthy installation that cleverly mounts in the spare tire area while offering maximum protection from the elements. Built to endure the toughest environments, this complete system provides the ideal balance of discreet original equipment manufacturer style mounting and high-output performance that serious truck builds count on.
