Hear these horns now!

EVER HAD KING KONG SCREAM IN YOUR FACE?

It doesn’t get much better than the Nathan AirChime K5LA. With our Nathan AirChime K5LA premium train horn kit, you get the loudest train horn on the market along with one of the most powerful onboard air systems! There is no substitute for the extremely loud and low rumble of an authentic Nathan Airchime K5LA train horn coupled with the insane performance of our 485C onboard air system. If you were looking for the best of the best, THIS IS IT! 

Setting the standard for what every train horn tries to be, our Nathan Airchime K5LA train horns are the real deal. The Nathan Airchime K5LA train horns are the most common train horn seen on locomotives since the ’80s and the sound is undeniable.  Massive in size and even more massive in tone, the Nathan AirChime K5LA train horn features five large die-cast aluminum bells with stainless steel diaphragms. Built to withstand years of use and abuse from the elements out on the track, you simply won’t find a more dependable train horn and the volume speaks for itself. 

When bringing these massive locomotive horns from the rails to the street, you better have an onboard air system that can handle them. That’s why we paired the Nathan AirChime K5LA Train Horns with our 485C onboard air system. With 5-8 gallons of air and the most powerful Viair compressor available, the Nathan AirChime premium train horn kit will give you an earth-shaking 5-8 seconds of honk time. The powerful Viair 485C stealth black air compressor provides this kit with a 100% duty cycle all the way up to 200 PSI, giving you a system that can power your locomotive horns, run air tools, and power air suspension without breaking a sweat!
