Train Horn

The Kleinn HK9-Slimline ProBlaster Triple Train Horn Kit stands as the brand's biggest and loudest train horn system, uniquely equipped with a slim-design 3-gallon air tank for a much easier installation profile. This massive system features the Demon Model 730's detachable XCR 2.0 spun steel trumpets measuring 18.25, 14.75, and 11 inches in length to allow for a wide variety of versatile mounting configurations. Powered by a high-output 150 PSI, 100% duty cycle waterproof compressor, this heavy-duty onboard air system includes a tire inflation kit with a storage bag and packs enough punch to support auxiliary accessories like air bags and small air tools. For ultimate performance, the system can be upgraded with an Ultra BlastMaster valve upgrade kit (P/N 6890), making it the loudest, largest, and most aggressive train horn setup on the market.
