Model HK3-1: Universal ProBlaster™ Black Compact Triple Air Horn System
Stop Being Ignored. Start Being Heard.
The Model HK3-1 is engineered specifically for drivers who demand maximum sonic impact and a discrete, "blacked-out" aesthetic. This system takes our best-selling platform to the next level by combining increased air capacity with a triple-horn configuration to produce a louder, richer, and more complex tone. Whether navigating busy city streets or rural highways, the HK3-1 ensures you have the presence of a much larger vehicle, making it the perfect upgrade for replacing a weak factory chirp with a professional-grade blast.
Professional-Grade Performance
At the heart of the system is the 6270RC 130 PSI waterproof air compressor paired with a 1-gallon internally coated steel air tank. This specialized internal coating is critical for preventing rust, ensuring your air supply remains moisture-free to prolong the life of your solenoid and horns. With a 25% duty cycle and integrated thermal protection, this rugged, oil-less system offers a "set it and forget it" solution for drivers who require dependable performance on demand.
Big Sound – Small Footprint
Installation is simple thanks to the kit’s clever, low-profile 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 HK3-1, you are joining thousands of drivers who trust Kleinn for superior quality and "get out of the way" authority. Don’t settle for a vulnerable factory horn when you can have the professional-grade power of the Universal ProBlaster™ Stealth.
WHY CHOOSE MODEL HK3-1?
- Triple-Tone Authority: Unlike standard dual-horn kits, the triple-trumpet design delivers a startling, high-pressure three-tone blast designed to pierce through the loudest traffic.
- Stealth Aesthetics: Featuring our signature Black XCR2.0™ Stealth finish, these horns are built to blend in behind your grille while remaining resistant to corrosion.
- Upgraded 130 PSI Power: We’ve boosted the output to a 130 PSI system, providing higher pressure for a louder initial blast and faster recovery times.
- Submersible Reliability: Equipped with the 6270RC waterproof air compressor, this system is designed to thrive in harsh environments, from off-road mud to coastal salt air.
- Longer Blast: The upsized 1-gallon air tank allows for double the hang time on the horn blast.
- Universal Fitment: The clever, low-profile design allows for a seamless fit in tight locations where traditional, bulky train horns simply won't fit.
