Kleinn Train Horn and Onboard Air Systems are designed with the serious truck owner in mind. The 100% Duty-Cycle system will supply air for inflating tires, powering air tools, air suspension and of course, honking your Kleinn Train Horns.  This kit includes a Kleinn exclusive heavy-duty WATERPROOF air compressor rated to 200 PSI , 3-gallon Made in USA air tank and custom-engineered direct fit mounting brackets. No vehicle modifications are required.

This kit includes the Demon™ model 730 triple train horn.  This is our largest and loudest train horn.  The black all-metal trumpets feature the XCR 2.0™ Anti-Corrosion Coating for good looks and long term durability.  The horns produce an earth shaking 157.8 decibels of genuine train horn sound. But wait! Want it louder?  Add the Ultra BlastMaster™ valve upgrade (P/N 6890).  This kit adds two additional high volume brass solenoid valves and a 1/2″ air line to each horn.

Kleinn kits are 100% Bolt-On and require no welding or vehicle modification*. You no longer need to spend hours designing and fabricating mounting brackets to install your air system and train horn. We’ve done all the design and fabrication for you

Included is a remote mount quick connect tire inflator with storage bag, all necessary hardware, air line and wiring.
