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.
BOOST YOUR BLAST: 30% MORE OUTPUT
Unleash the full fury of the Titan™ 630 Horns!
Push the 630 Titan™ train horns to the edge of sanity with the Ultra BlastMaster™ (Model 6880). This upgrade adds two additional Model 307 high-flow solenoids and swaps the standard tubing for a massive 1/2" airline.
The result is bone-rattling decibel levels that demand respect across entire city blocks. Experience the 630 Titan in its most aggressive form—because "TOO LOUD" happens to be just right.
TOO LOUD? TOO BAD!
