This bad boy is for everyone who told Kleinn they wanted a louder, nastier train horn. This horn is called the beast, that should tell you right there THIS HORN IS LOUD! The flat-rack design requires 40% less clearance than our 500 Series train horns. The trumpets can be separated from the mounting brackets for installation in vehicles that could not otherwise fit full-size train horns. This Train Horn Kit from Kleinn Automotive includes everything you need for a complete train horn install on your vehicle. Kits include horns, compressor, tank, wiring, air tubing and switches. There is no mistaking the that genuine train horn sound. Kleinn Automotive manufactures the loudest and highest-quality horns on the market.
