Kleinn - Ford Bolt-On Train Horn - VELO-734

 

The Kleinn Direct-Fit “Demon” Train Horn & Onboard Air System is designed for truck owners who want maximum train horn performance without custom fabrication. It delivers an earth-shaking locomotive blast while providing a fully integrated onboard air system tailored to specific vehicles.

Built around the powerful Model 730 “Demon” triple train horns, this system features large stainless steel trumpets that produce a deep, harmonic tone with extreme output. Combined with a high-performance compressor and properly sized air tank, it ensures consistent, powerful blasts with fast recovery.

Additional features include a 150–200 PSI waterproof compressor (100% duty cycle), a vehicle-specific mounting system, and precision-engineered brackets that allow installation in optimized locations such as frame rails, underbody, or spare tire areas depending on the application.

Engineered with true vehicle-specific fitment, each kit is designed for seamless integration with select trucks—eliminating the trial-and-error of universal systems.

Installation is typically a direct bolt-on process using included brackets and hardware, making it significantly easier than universal horn kits while maintaining a clean, factory-like appearance.

Whether you're upgrading for towing safety, off-road presence, or the loudest possible horn system, this direct-fit solution delivers unmatched performance and convenience. Now Available at LEER!
