The Kleinn HK9 ProBlaster Triple Train Horn Kit stands as the brand's ultimate, biggest, and loudest train horn system, featuring the Demon Model 730's massive and detachable XCR 2.0 spun steel trumpets measuring 18.25, 14.25, and 11 inches in length with a mounting base that adds an additional 3.5 inches. Engineered to allow for a wide variety of versatile, individual, or combined installation configurations, this heavy-duty system is powered by a high-output 150 PSI, 100% duty cycle waterproof air compressor paired with a massive 5-gallon steel air tank. Complete with a bonus tire inflation kit and storage bag, this robust onboard air setup packs more than enough punch to power your horns alongside auxiliary accessories like air bags and small air tools, and for maximum performance, it can be upgraded with an Ultra BlastMaster valve upgrade kit (P/N 6890) to create the loudest, largest, and most aggressive train horn setup available on the market.
