Upgrade your truck with the Kleinn train horn and onboard air system, engineered specifically for owners who demand premium quality and precision vehicle-specific fitment. This premium heavy-duty kit features a true 100 percent bolt-on installation with direct-fit, vehicle-specific mounting brackets that guarantee a clean under-truck layout with absolutely no cutting, welding, or drilling required. This complete package comes with all necessary high-grade air lines, wiring, and hardware to ensure a seamless, professional-looking setup right out of the box. This high-performance system features the legendary, earth-shaking blast of our Beast model 230 train horn. Providing the pneumatic power is a high-output model 6350RC 150 PSI waterproof air compressor paired with a durable, powder-coated steel three-gallon air tank to ensure rapid recovery times and dependable, long-term performance. This versatile setup creates an onboard air station capable of inflating large tires, powering air tools, or operating air suspension bags. For maximum utility on the go, the system comes equipped with a remote-mount quick-connect tire inflator complete with a dedicated storage bag. For drivers who want to command even more attention on the road, the horns can be upgraded to be significantly louder by adding the part number 6885 BlastMaster Plus valve upgrade kit. 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 custom builds count on.
