Kleinn 20-26 Chevrolet Silverado 2500 HD/ 3500 HD Onboard Air System w/ Model 730 Horns
Dominate the road with the ultimate train horn and onboard air system. If you are looking for the loudest train horn for your truck alongside an onboard air system that delivers extreme power and unmatched reliability, this setup is built for you. This system is not for the timid, it is engineered specifically for drivers who want to command attention, turn heads, and run the most powerful train horn kit on the road. This direct-fit, 100 percent bolt-on train horn and onboard air system is engineered for maximum performance with zero hassle, requiring no drilling and no fabricating for pure, unapologetic power.At the heart of this system is an exclusive 100 percent duty-cycle waterproof air compressor, paired with a high-capacity, anti-corrosion-coated air tank built for long-term durability. When you hit the switch, the XCR 2.0 black-coated Demon stainless steel train horns unleash a blast so loud and aggressive it rivals a real locomotive, making it one of the loudest train horn kits for trucks on the market.True direct-fit installation means every component mounts cleanly under your truck using precision-engineered, powder-coated brackets that bolt directly to factory locations. This guarantees no drilling, no guesswork, no cutting, and an OEM-clean fitment for a stealthy, rock-solid installation that hits like a freight train.Built for long-term performance, every hose, fitting, and accessory is designed for long-term punishment and minimal maintenance. This complete kit includes a heavy-duty air hose, quick-connect fittings, a glow-in-the-dark inflator gauge, and all wiring and hardware needed for installation. For those who want even more power, you can add the BlastMaster Upgrade Kit (Model 6890) for a 30 to 40 percent increase in volume. This upgrade gives each horn its own dedicated heavy-duty brass solenoid and half-inch airline for maximum airflow and maximum output, making your setup one of the loudest aftermarket train horns available.
