Model HK6: Universal Tri-Mount Chrome ABS Train Horn Kit

The Legendary Kleinn Locomotive Blast—Reimagined for Smaller Rigs

Don’t let the compact footprint fool you; the Model HK6 delivers a massive, earth-shaking impact that lives up to the Kleinn legacy. This system produces a deep, authentic locomotive blast by utilizing three tuned, chrome-plated high-impact ABS trumpets with a single, right-angle, tri-mount design. These horns provide a rich, multi-tonal chord for a blast that's a great introduction to the super-loud club.

Unrestricted Airflow for Maximum Volume

To ensure every decibel is accounted for, the system is engineered for high-volume output. By providing a dedicated, high-pressure air path to the Vortex 4 solenoid, the HK6 allows for unrestricted airflow and a startlingly loud,1 50+ dB blast that rivals much larger, more expensive systems. When these horns sound, there is no mistaking that genuine train horn authority.

The Compact Powerhouse

The HK6 is the ultimate solution for vehicles where mounting space is at a premium—such as smaller trucks, SUVs, or Jeeps—but a commanding "get-out-of-the-way" presence is non-negotiable. This system bridges the gap between size and strength by pairing our high-performance 150 PSI waterproof compressor with a larger-capacity 1.5-gallon air tank. The result? A consistent, high-pressure air supply that fuels the deep, locomotive-style rumble only a true triple-train horn can produce. Now you can command the road with the authentic Kleinn blast and brilliant chrome aesthetics without the need for a massive, space-hungry footprint.

WHY CHOOSE MODEL HK6?

Big sound, small price, zero compromises.

  • Tri-Mount Chrome Design: Featuring three high-impact ABS trumpets integrated into a single heavy-duty air block with a right-angle mounting bracket, this system is engineered for maximum durability and a massive, multi-tonal locomotive blast. Its lightweight, compact architecture allows for a seamless, bolt-on installation across a wide variety of vehicle applications.

  • 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.
