    Explosive Sound. Upgrading to a triple train horn like the Model 630 from Kleinn is a great way to make sure you're heard on the road or noisy work site, but sometimes it's still not enough sound. Pump up the decibels even further with the Blastmaster valve upgrade kit which splits the air supply so that each horn gets an increased pressure, resulting in louder sounds.

    Tough Construction. This kit's 1/2-inch air hose is made from heat and chemical resistant nylon so it can last years of exposure to the elements and engine compartment challenges. The brass fittings are also corrosion resistant for durability.

    Extra Solenoids. Not only do the new valves and extra airline change how much pressure is distributed to each horn, the extra solenoids increase the power to your Kleinn aftermarket train horn as well. You'll notice the difference from the first time you need to honk at a hazard in the road.

    Application. This Kleinn Blastmaster Valve Upgrade Kit pairs with Model 230 or 630 installed on any 2007 to 2018 GMC Sierras.
