The Kleinn ProBlaster Dual Air Horn Kit (HK2 / HK2-1) is designed for drivers who want a complete air horn system with more power and deeper tone than compact mini kits. It delivers a strong, attention-commanding 2-tone blast while maintaining a manageable footprint for most vehicles.
Built with all-metal trumpets (chrome or black XCR2.0 finish), this system provides excellent durability and resonance for a fuller, more aggressive sound. The longer trumpet design produces a deeper tone compared to smaller kits, making it ideal for trucks and larger vehicles.
Additional features include a 120 PSI sealed compressor, a 0.5-gallon steel air tank with corrosion-resistant coating, and a snorkel intake system for cleaner air supply. This ensures consistent performance even in harsh driving conditions.
Engineered with universal fitment, the HK2 kit can be installed in a wide range of trucks, SUVs, Jeeps, and custom builds.
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, daily driving, or a louder, more commanding presence, this kit delivers serious performance in a compact system. Now Available at LEER!
