Hear these horns now!

A 5-chime train horn kit fit for royalty! Our King 5 540 Train Horn Kit is a complete train horn kit designed for anyone wanting to be king of the road. Large, loud and with a tone that will peel the paint of a wall, our King 5 540 Train Horn Kit will ensure everyone else on the road bows down before you. 

A budget-minded alternative to the Nathan AirChime to the more expensive Nathan AirChime Train Horns, our King 5 Train Horn gives you the imposing presence and power of an authentic locomotive horn without the hefty price tag. While they are just as loud as the real deal, they’re not tuned to the US Train Horn Chord, so if you are looking for something just as loud that sounds different than every other train horn out there, our King 5 540 Train Horn Kit is right down your ally! 

We bundled this beast of a horn with our PSI HornAir 540 Onboard Air System to give it all the power it needs to be heard from miles away. In addition to giving you up to 10 seconds of continuous blast time for your King 5 Train Horn, this kit may also support other onboard air applications such as tire inflation in an emergency situation. Our Black 5 Gallon 8 Port Air Tank is powered by a Viair 400C Fast-Fill Air Compressor, giving this kit one of the fastest fill times available, recharging our 5-gallon tank from 110-150 PSI in 1 minute and 30 seconds while only pulling 28 amps from your battery. 

While this kit gives you everything you need to get up and going, make sure to pick up our tire inflation kit, wireless remote and mounting bracket to get the most out of one of the best train horn kits you can buy.
