Gavan's 1995 Jeep Wrangler features one of the loudest horns ever made, the Nathan AirChime K3LA. This variation of the K3 is an actual railway-use horn used on many commercial train lines in the USA. If you’ve heard a diesel locomotive barrelling down its tracks and blowing its horn, then more than likely this is the same horn you’ve heard. This kit contains everything you need to install it on any vehicle. An extremely loud train horn that is still in use on real locomotive engines, a five gallon air reservoir to supply lots of air, a fast-fill air compressor to ensure fast refill rates, and all fittings and accessories needed to ensure stable and long term use!
