HornBlasters Shart 232 Air Horn Kit


  • You’ll know it when you hear it! Paired with an impressive 2-gallon air system! The 2 gallon (7.6 liters) tank can recharge from 110 to 150 PSI in just under 50 seconds! This is because we matched Viair’s flagship medium duty quick-recharge compressor, the 325C. This pump is powerful and comes with Viair’s impressive reliability and warranty. The air system features everything you’ll need to have an extremely loud horn kit up and running in no time; including, a weatherproof pressure switch with built-in relay, all the fittings, and airline you’ll need, and of course the wire and terminals to get it all hooked up. This complete train horn kit is ridiculously loud! This kit does come with the option to add our Tire Inflation Kit to it as well!

    So maybe you have a big truck or SUV with a wimpy stock horn, or maybe you have a car and need some extra attention on the road, or maybe you just want to have a ridiculously loud horn! No matter what your reason is, this horn kit is the answer: you get unparalleled Shocker XL performance, paired with a powerful 260-watt air system, and the kit fits on just about anything.
