This horn blows!

WOW!!!!! That’s the best description I can come up with. This was a Christmas gift from my wife. Let me tell you, I can’t stop smiling every time I press that button. This horn will wake the dead. Super loud and install wasn’t too difficult. Just wish I would have got the stealth STD kit.


My new train horn

I installed on my 2023 Chevy 2500HD HighCountry CONDUCTOR'S SPECIAL 232 TRAIN HORN KIT. This is one loud horn I went with two tanks and electric drain valve.

Best Christmas Gift Ever....

Amazing kit... My father and brother decide to surprise me with this kit after I mentioned buying one after the holidays. Tried to get it set up the weekend after Christmas but ran into a couple of snags. Finally got it installed yesterday and I love it (pretty sure my neighbors might hate me sooner or later) it's loud and gets it's point across.. easy as pie to install but I do recommend having an extra set of hands around if you can. Got it done in about 4 hours by myself. Tank and compressor are in bed of my Ram 1500 and horns are behind front bumper on a plate secured to Tow Hook mounts at front of frame. I absolutely recommend this kit to anyone looking to make some noise, protect their investment and have a few laughs...
