Kleinn Air Horns HK9-Slimline Problaster Ultimate Triple Train Horn Package -with Blackhorns, 3-Gal Tank and 150-PSI Heavy Duty Sealed Air System

OMG! These horns are "the bomb" .. I had them expertly installed by Alamo Trucks (San Antonio) on my 2017 F350 dually and they sound awesome; rich, powerful, and LOUD! There is no "kit" for the 2017 Super Duty trucks and the only place the horns fit was below the driver seat, facing the rear of the truck. The compressor sits below the rear, driver side, passenger seat (both under the truck, of course). The rear facing horns are NO problem as they are so loud. The 3 gallon air tank is good for about three solid blasts before the compressor kicks on. You will hear the compressor, but it's a temporary annoyance. I do suggest the option to use just the standard truck horn, as these horns are really too loud to, for example, hail someone you're picking up, or letting someone in the house know you're waiting outside. I have my compressor on one upfitter switch and the horn on another (they both stay on most of the time :-) ) .. This way I can turn the air horns off and still use the air compressor, or turn both off to prevent the compressor from depleting my battery if the truck sits for a while. I highly recommend these horns and am very satisfied!

If you want a loud great sounding train horn this game me is it. I have this horn in my truck and my motorhome. Great quality and sound

Much louder then I thought it would be.
