Model HK3: Universal ProBlaster™ Chrome Triple Air Horn Kit

Stop Being Ignored. Start Being Heard.

The Model HK3 is engineered specifically for drivers who demand maximum sonic impact and a sharp "mirror-like chrome" 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 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, 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™ Chrome.

 

WHY CHOOSE MODEL HK3?

  • Triple-Tone Authority: Unlike standard dual-horn kits, the triple-trumpet design delivers a startling, high-pressure tri-tone blast designed to pierce through the loudest traffic.
  • Sharp Classic Look: Featuring our signature Premium Chrome finish, these metal air horns are built to blend in behind your grille or fit neatly under the chassis 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.
