Looking for the loudest air horn kit we sell? You found it! Our Rocker 127H air horn kit was designed to pack enough power to rock your world while being compact enough to fit in most vehicles. Perfect for smaller vehicles where the air source system will be kept in a trunk or a toolbox, you will not find a louder horn kit this compact anywhere else!
Our Rocker air horn that is included in our Rocker 127H air horn kit is the loudest air horn on the market. Our Rocker air horn consists of two of the four bells of our classic Shocker XL train horns and still packs the same amount of punch. Constructed from an ultra-durable fiberglass-reinforced ABS composite with stainless-steel diaphragms and backed by a limited lifetime warranty against manufacturer defects, our Rocker air horn is not only the loudest air horn you can get but are also some of the most durable.
Powering our Rocker air horn is our 127H Air Source Unit. The 1.5-gallon tank comes pre-wired and pre-plumbed with a mounted Viair 275c air compressor, providing 3-4 seconds of honk time and recovers the tank in about 30 seconds! As most of the wiring and plumbing is already done for you, this kit is perfect for beginners or vehicles with limited space. Our Rocker 127H air horn kit comes as a complete kit with hardware and instructions included.
(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... Failure to mount this product as directed will void the warranty)
**Detaching the compressor from the tank will void your warranty on this kit. If you need a solution where the compressor is detached, please look at our 232 and higher models. **
