Just finished installing the Klein Air Horns GMC 1500-230 direct fit air horn on my truck. it gives us an on board air system that allows us to fill our tires and use air tools and gives us a very loud train horn #kleinnairhorns #tooloudtoobad #gmc1500-230 #trainhorn

Kleinn train horns are super loud. My bro has these on his truck and man they're loud. I think he has the HK3 model.
