The Kleinn HK6 “Sentinel” Triple Train Horn Kit is designed for drivers who want authentic train horn performance in a compact, easy-to-install system. It delivers a powerful multi-tone locomotive blast while maintaining a footprint small enough for trucks, SUVs, Jeeps, and tight mounting locations.
Built with chrome-plated high-impact ABS trumpets, the HK6 offers excellent durability while remaining lightweight and corrosion-resistant. The three tuned trumpets (16", 14", and 11") create a rich harmonic chord that closely mimics a real train horn.
Additional features include a 150 PSI air system, a 1.5-gallon steel air tank, and a Vortex™ solenoid that delivers unrestricted airflow for maximum output. This setup ensures consistent pressure and strong, sustained blasts.
Engineered with universal fitment, the tri-mount design allows installation behind grilles, along frame rails, or in other tight spaces where larger systems won’t fit.
Installation is typically a straightforward bolt-on process with included wiring and hardware, making it suitable for both DIY and professional installs.
Whether you're upgrading for safety, towing visibility, or stepping into true train horn performance, the HK6 delivers serious output in a compact package. Now Available at LEER!
