The Kleinn SDKIT17-734STL train horn and onboard air system is the perfect solution for Ford Super Duty owners who have lifted their truck and are running oversized tires, installed an aftermarket bumper, or added a behind-the-bumper winch. Designed specifically for modified vehicles where traditional mounting space is limited, this premium kit features a custom-engineered bracket that bolts directly into the location where the factory spare tire would normally be housed. The system includes the legendary, earth-shaking blast of our Demon model 730 steel triple train horns, delivering unmatched volume and performance. Providing the pneumatic power is a heavy-duty, 100 percent duty-cycle waterproof air compressor paired with a generous three-gallon air tank, creating a versatile onboard air station. The comprehensive kit comes complete with every single part needed for a simple, true 100 percent bolt-on installation using existing factory holes with absolutely no cutting, welding, or drilling required. For enthusiasts looking to maximize their sonic output, the entire setup can be upgraded to deliver a 40 percent louder blast by adding the part number 6890 BlastMaster valve upgrade kit. Built to endure the toughest environments, this package provides the ideal balance of clever, out-of-the-way mounting and high-output performance that serious custom truck builds count on.
