Model HK2-1: Universal ProBlaster Black Dual Air Horn System
Time to Retire the Wimpy Factory Horn
The Model HK2-1 is engineered specifically for drivers who demand maximum sonic impact and a discrete, "blacked-out" aesthetic without sacrificing valuable mounting space. This system provides the ultimate value by packing the raw, commanding authority of an emergency vehicle horn into a compact, streamlined package. Whether you are navigating busy city streets or rural highways, the HK2-1 ensures you have the presence of a much larger vehicle, making it the perfect upgrade for those looking to replace a weak factory chirp with a professional-grade, high-impact blast.
Professional-Grade Performance
At the heart of the system is the high-performance 6270 waterproof air compressor paired with dual trumpets featuring our signature Stealth Black finish. This heavy-duty combination is not only built to withstand the harshest elements but also provides a sleek, muted look that disappears behind your grille. The 120 PSI air system is optimized for rapid recovery and includes a 0.5-gallon inner-coated steel tank, ensuring you always have a reliable air supply ready whenever you need to make your presence known. It’s a rugged design prioritizes durability and consistent performance in virtually any environment.
Big Sound – Small Footprint
Installation is made simple thanks to the kit’s clever, low-profile, stealth black design. The compact footprint allows for a seamless fit in tight locations, such as behind the grille or tucked neatly inside the engine bay, where traditional train horns simply won't fit. By choosing the HK2-1, you are joining thousands of drivers who trust Kleinn for superior quality and loud, dependable results. Don’t settle for a vulnerable factory horn when you can have the professional-grade power and "get out of the way" authority of the Universal ProBlaster™ Stealth HK2-1.
WHY CHOOSE MODEL HK2-1?
- 2-Tone Authority: Unlike the shorter 101 horns, these longer trumpets create a deeper tone that delivers a startling, high-pressure 2-tone blast designed to pierce through the loudest traffic and heavy machinery from construction.
- Industry-Leading Submersible Waterproof Compressor: Drive with total confidence through river crossings or monsoons by drawing air from inside the vehicle. This fully waterproof unit delivers an impressive 1.56 CFM flow rate for rapid recovery.

- Compact Integration: The low-profile design allows for a seamless fit behind the grille or tucked inside the engine bay.
- Advanced Corrosion Resistance: The 0.5-Gallon air tank is treated with an internal anti-corrosion coating, preventing internal rust and ensuring a clean, moisture-free air supply for your accessories.
