Premium Air Horn for Big Diesel Trucks

If you’re looking to make a serious statement with your truck, the Kleinn Pro Blaster Triple Train Horn Kit delivers the kind of volume that turns heads and clears paths. Designed for truck owners who want more than just a loud horn, this complete kit includes everything you need to bolt up a real-deal train horn system, backed by a robust onboard air setup that’s ready for action. At the heart of the kit is a triple-trumpet train horn, molded from high-impact black ABS and tuned for deep, authentic sound. The trumpets measure 17.5", 14.5", and 11.5" and can be mounted together on the flat rack or separated for custom installations—ideal for tight spots where full-size horns normally won’t fit. Whether you’re warning traffic or just having some fun, this horn packs serious punch.

High-Quality Construction & Design

To keep the system running reliably, Kleinn includes a waterproof 150 PSI air compressor with a 100% duty cycle, meaning it’s built to run long and hard without overheating. The 3-gallon air tank provides plenty of reserve for repeated blasts and comes pre-plumbed with all the essentials: pressure switch, safety valve, drain, and outlet fitting. You also get 12 feet of high-pressure nylon tubing, a tire inflation coil hose, and even a horn button—making this a truly complete package. Everything is built for durability and long-term use, whether you’re mounting it on a daily driver or a full-time off-road rig. And if you ever want to push the volume even further, you can upgrade to the Ultra Blastmaster Valve Kit for even more airflow and intensity.
