Our 500 Series kit makes train horns sound the way they are supposed to! The ample 5 gallon air supply powers them at 150 PSI bringing out the loudness but still keeping the horn sound beautiful at its designed tones.

The included 400C compressor is the fastest 150 PSI compressor we carry and perfect for train horns. The air system can recharge itself from 110 to 150 PSI in just 1 minutes and 38 seconds.

Package comes with everything you need to install a fully functional air system on your vehicle.


  • Designed for extreme Train Horns
  • All-inclusive Train Horn air solution!
  • Top-End 150 PSI compressor perfect for Train Horns
  • Comes with standard 1/2 in push-to-pull fitting
  • Complete Fitting Kit with safety valve & drain cock
  • All standard mounting hardware


Seriously Powerful:

This kit is designed for large applications, whether it be full size train horns or heavy use for air tools, tire inflation, or any other mobile air application, this is the ultimate kit.

This package is perfect for filling up load leveling air springs. If your truck has air springs without a compressor setup, this is the perfect compliment. Please note that if you use horns, you will still need an air spring kit to connect the system properly.


Unlike some other air systems, Horn Air kits come with 10 and 18 gauge wire, and a complete wiring kit including a fuse holder. This takes out the guess work on your end and makes sure your system is installed correctly.  They also come with a standard 1/2in OD push-to-pull fitting. This means the horns you hook up with get all the air they need.
