KING 5L 540 D

Powerful, insanely loud, and all in a compact kit: the Shocker 540 train horn kit delivers the performance you need. The Shocker 540 features the insanely loud, American-made, Shocker Horns. These horns are ridiculously loud and, more importantly, actually sound like a train! The horns are hand-tuned in the USA to the government mandated train signal chord. Simply put, they sound completely authentic. With the 4 horns being individually mounted they are the most versatile when it comes to mounting. The horns can be scattered out and mounted in just about any configuration needed. Coupled with these impressive horns is an even more impressive air system. This air system was designed from the ground up to work amazingly with train horns and it does just that. The 5-gallon tank can recharge from 110 to 150 PSI in just 1 minute and 45 seconds! This is because we matched Viair’s highest performing compressor in its class, the 400C. This pump is powerful and comes with Viair’s impressive reliability and warranty. With this being a fast fill compressor it doesn't have a very long duty cycle. Meaning the compressor can fill the tank fast but cannot be running for long amounts of time. The system is mainly meant for just the train horns but can be used for any pnuematic use in an emergency situation. With the 110/150 PSI pressure switch with a built-in relay included in the kit, it will kick the compressor on when the system drops below 110 PSI. Then when the system reaches 150 PSI it will turn the compressor off. Making this a completely self-contained unit. The relay acts as a shield for the pressure switch by taking most of the amp draw. Wiring the pressure switch and relay correctly will also allow the system to only run while the vehicle is on as well. Meaning the only thing you ever have to do is make sure to drain the tank of moisture on a regular basis!
