ULTIMATE SERIES NATHAN AIRCHIME K5L

The Ultimate 12HB Train Horn Kit is Hornblasters' most powerful and capable kit to date, designed for maximum volume, long blast time, and flexible onboard air usage. This system allows for a choice between the brand-new King 5 or a reconditioned Nathan Airchime K5 train horn, both full-size five-chime horns with massive output. The kit is suitable for daily drivers, show trucks, and off-road builds. It includes either the King 5 (die-cast, unmatched clarity) or the Nathan K5 (from real locomotives, restored for authentic tone and volume), a 12-gallon air tank with seven half-inch and one three-quarter-inch ports (rated for 150 PSI with a 300 PSI burst), and four constant-duty compressors for fast tank filling and quick recovery.
