The Kleinn HK5 “Mini Beast” Dual Train Horn Kit is designed for drivers who want true train horn performance in a compact, install-friendly system. It delivers a deep, commanding locomotive blast while maintaining a footprint small enough for trucks, SUVs, Jeeps, and tight engine bay installations.
Built with high-impact ABS trumpets and heavy-duty zinc alloy drivers, this system offers excellent durability while remaining lightweight and corrosion-resistant. The dual wide-bell horn design creates a deep rumble that closely mimics a full-size train horn.
Additional features include a 150 PSI waterproof compressor, a larger 1.5-gallon air tank, and a snorkel intake system for clean airflow. This setup provides consistent pressure and longer, more sustained blasts compared to smaller kits.
Engineered with universal fitment, each horn mounts individually, allowing flexible installation in tight or unconventional spaces.
Installation is typically a bolt-on process with included wiring and hardware, making it suitable for both DIY and professional installs.
Whether you're upgrading for safety, off-road presence, or a true train horn sound, the Mini Beast delivers serious performance in a compact system. Now Available at LEER!
