Model HK3: Universal ProBlaster™ Chrome Steel Triple Compact Air Horn System
TRI-TONE CHROMED RESONANCE
The Model HK3 is engineered specifically for drivers who want a classic blend of screaming loud horns and a premium chrome aesthetic without sacrificing valuable mounting space. This complete system delivers the raw, commanding authority of an emergency vehicle horn in a compact, streamlined package. Whether you are navigating busy city streets or rural highways, the HK3 ensures you have the presence of a much larger vehicle—perfect for replacing a weak factory chirp with a professional-grade, high-pressure blast.
BIG SOUND – SMALL FOOTPRINT
Installation is simple thanks to the kit's clever, low-profile horn 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 oversized train horns simply won't fit. Featuring our signature Chrome-Plated Trumpets, these horns are built to withstand salt spray, road debris, and the harshest environments. This system bridges the gap between size and strength by pairing our high-performance 130 PSI air compressor with a compact 1-gallon air tank reservoir.
WHY CHOOSE MODEL HK3?
- 3-Tone Authority: Three synchronized chrome trumpets create a resonant, harmonic chord that delivers a startling, high-pressure blast designed to pierce through loud traffic and heavy machinery.
- Upgraded 130 PSI Power: We’ve boosted the output to a 130 PSI pneumatic infrastructure, providing higher operational pressure for a louder initial blast and faster recovery times between uses.
- Mirror-Like Chrome Finish: Finished in a specialized chrome coating, these steel trumpets make a premium high-profile visual statement while providing structural resistance to environmental elements.
- 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 paths.
- Vortex™ 4 Solenoid Included: Model HK3 horns are pre-fitted with our model 307 12V electronic chrome solenoid valve for instantaneous air delivery and maximum volume.
- Complete All-in-One Solution: This comprehensive configuration incorporates Model 130 Triple Compact Horns, a high-performance compressor, a 1-gallon air reservoir, an automated pressure switch, wiring, and high-strength hardware blocks.
THE VERDICT: The Model HK3 ProBlaster™ serves as the ideal intermediate entry point for truck, SUV, and Jeep builds that demand highly resonant chrome aesthetics and emergency vehicle presence without taking up oversized undercar structural real estate.
