Model HK8: Universal "Titan" Chrome Steel Triple Train Horns / Onboard Air System

PROFESSIONAL GRADE CHROME AUTHORITY

For the driver who demands a professional-grade locomotive blast with the classic chrome aesthetic, the Titan™ Model HK8 has arrived. Engineered to outperform everything in its category, the high-impact steel construction of the Model 630 Titan™ horns delivers a sharp, aggressive, multi-tone chord. The HK8 cuts through road noise with surgical precision, providing the signature Kleinn locomotive-style blast that defines a true statement of authority.

THE PRACTICAL PNEUMATIC POWERHOUSE

The Model HK8 delivers elite performance without the bulk. Driven by the industry-exclusive Model 6350RC Waterproof Air Compressor, this system is more than just a horn—it’s a professional-grade onboard air command center. Whether you are delivering a deafening blast, inflating 35” tires, managing air bags, or engaging lockers, the HK8 provides high-pressure pneumatic power exactly when you need it.

VERSATILE MOUNTING OPTIONS

The Model HK8 is a lightweight, versatile system featuring the popular Model 6350RT 3-Gallon Air Tank internally coated for superior corrosion resistance and designed for a high-capacity/small-footprint balance, this tank is perfect for easy frame-rail or under-body mounting. For maximum installation flexibility, the detachable chrome steel horns can remain on the included flat rack mounting plate or be removed and mounted individually to fit tight spaces.

WHY CHOOSE "THE TITAN" HK8?

  • The Titan™ (630) Chrome Train Horns: Precision engineered with three Chrome Steel Trumpets, these horns deliver a massive, authentic multi-tone locomotive blast. Built for the long haul, they combine "heavy metal" trumpets with a chrome-plated finish for ultimate durability.
  • Industry-Leading Submersible Waterproof Compressor: Drive with total confidence through river crossings or monsoons by drawing air from inside the vehicle using the snorkel kit provided with the compressor.
  • Maximum Output: With a consistent 150 PSI pressure design and a high-flow 2.11 CFM flow rate, this system is engineered for high-impact, authoritative horn performance. The 100% duty-cycle rating ensures the compressor is perfect for high-impact, loud, and authoritative blasts.
  • Space-Saving Design: Engineered with an optimized footprint for a seamless fit in almost any vehicle. The versatile flat rack architecture allows you to install the system as a single unit or mount each horn individually for maximum flexibility.
  • Multi-Purpose Utility: Not just for horns—use the powerful onboard air system for tire inflation up to 37", managing air suspension / air bags, and small air tools. Includes the INF-1 inflator kit with a 24’ heavy-duty air hose and tire inflator.
  • Advanced Corrosion Resistance: This 3-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.
  • Complete All-in-One Solution: This comprehensive kit includes Model 630 "Titan" Triple Train Horns, high-performance 6350RC waterproof compressor, and 6350RT 3-gallon air tank. It comes fully loaded with a sealed pressure switch, wiring, and hardware.

THE VERDICT: The Model HK8 "Titan™" is the definitive choice for drivers who demand a professional-grade blast and rock-solid reliability. The Titan 630 horns deliver the authentic roar of locomotive excellence without the "Demon" HK9 price tag.
