Our biggest train horn kit! The HK9-Slimline has all the same features as the HK9 kit but includes a slim design 3-gallon air tank and not the larger 5-gallon tank. The slim design tank offers more mounting options on small and mid-size trucks and SUVs. The Demon™ Model 730’s massive and detachable XCR 2.0™ spun steel trumpets (18.25”, 14.75”, 10.5”) allow tons of installation options. Includes a fully submersible waterproof high output 150 psi, 100% duty compressor and tire inflation kit with storage bag.
The 730 can be upgraded by adding the Ultra BlastMaster™ valve upgrade (P/N 6890) – making it the loudest, largest and most aggressive train horn on the market.
