Need a powerful air horn set-up to make sure the crazies stay out of your way when you are out on the road? With our PsychoBlasters 127H air horn kit, you get a complete kit with a horn loud enough to drive everyone mad. Our PsychoBlasters 127H was designed with the beginner horn enthusiast in mind, giving you all the power you need to be heard while keeping things simple and cost-effective.

Few horns are as painful to listen to as our PsychoBlasters air horn. This dual-chime chromed-out beast delivers a high pitch wail that is sure to get you noticed. With its higher tone that cuts through road noise and extreme volume, it’s no surprise that our PsychoBlasters Air Horns are some of the most popular air horns that we carry. Beginner friendly, our PsychoBlasters comes pre-plumbed with the required 1/4" air valve to streamline installation. 

The PsychoBlasters air horn coupled with our HornAir 127H onboard air system creates one of the best entry-level air horn kits that you can buy. Our PsychoBlasters 127H gives you an easy-to-install, compact kit that keeps cost low without sacrificing performance. Our 1.5-gallon air tank provides you with enough air to get up to 3 continuous seconds of blast time and the lighting-fast Viair 275C air compressor will recharge the tank from 90-110 PSI in a stunning 35 seconds! Our PsychoBlasters 127H comes pre-plumbed and pre-wired, making installation much quicker and easier than other complete kits. 

  • All-inclusive air horn solution!
  • Beautiful chrome finish
  • Complete with pre-installed air valve & fittings
  • 120 PSI air system
  • Max honk time: 4 to 6 seconds

(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. **

Sounds great. Loud.

Was good. A push button instead of a toggle switch I think would be better. I left factory horn on.

This kit is an absolute blast!! (No pun intended!) The loudness and tone of this horn will make sure anyone that cuts you off instantly regrets it! The other day I had a young lad on his cellphone pull out in front of me, and with one quick blast his phone dropped and he was instantly paying attention to the road. He may have soiled his shorts after that one, thank you Hornblasters!
