Always pushing the boundaries of performance and power, it was only a matter of time before we came out new kit that would beat out all of the others. With our Nathan Airchime 8485K Train Horn Kit, a new train horn kit reigns supreme as the best train horn kit we have to offer. We took the loudest horn that you can buy and paired it with our most over-the-top and overpowered onboard air system yet.

There really is no substitute for the real deal. The Nathan AirChime K5LA Train Horns that are featured in this kit are the loudest horns that you can fit on a vehicle. The same exact train horns that are used on most locomotives today, the Nathan AirChime K5LA Train Horns is a 5-chime die-cast horn that produces a thunderous roar that is easily recognizable as the classic train horn tone that has been on most trains since the 80S. Designed to be heard for miles and withstand all the abuse that mother nature can dish out for decades at a time, you won’t find a more powerful and durable train horn. 

These massive horns are powered by our equally powerful HornAir 8485 Onboard Air system. As the most powerful onboard air system that we have ever delivered in a complete kit, the Nathan Airchime 8485K Train Horn Kit is more than equipped to handle the largest of train horns, as well as tire inflation, air suspension, air tools, and any other pneumatic task to need to accomplish. Our giant 8-gallon tank will supply you with plenty of air to work with as well as give you Nathan Airchime K5LA Train Horns a solid 8 continuous seconds of blast time.  Dual Viair 485K Air Compressors power the system, giving the Nathan Airchime 8485K Train Horn Kit a 100% Duty Cycle all the way up to 200 PSI and will recharge your 8-gallon tank from 110-150 PSI in just over a minute and a half! 

Our Nathan AirChime K5LA Train Horn comes standard in a Painted Black Finish. Make sure to select the Black Powder Coat Finish option on the drop-down menu to give your investment a sleek and professional black powder coat finish that keeps your Nathan AirChime K5LA Train Horn more protected from the elements!
