The Shocker 240 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.
Coupled with these impressive horns is a HornAir 240 air system. This air system was designed from the ground up to work amazingly with train horns and it does just that. The 2 gallon (7.6 liter) tank can recharge from 110 to 150 PSI in just 40 seconds!
