HornBlasters Jackass 127H Air Horn Kit


  • Catch them by surprise! The Jackass horn will wipe the smile off anyone's face. Insanely loud and small enough to fit on just about anything this kit brings the Jackass horn to life.

    Put it on your car, truck, or even quad and let ’em have it! Everything you need is in the box ready to be installed. The unit pulls just 18 amps at peak performance and can recharge its tank in 35 seconds.

    * Our wiring kit includes 17ft of both 10 and 18 gauge wire, an inline fuse holder, toggle switch, relay, and all electrical terminals needed to hook the system up.(Note: Tank mounted air compressors are not fully sealed.  For this reason, the manufacturer recommends the tank/compressor system be mounted in the upright position in an enclosed space away from moisture, dirt, debris, etc...)
