WE COULDN'T GET JOHNNY KNOXVILLE

Get ready to turn heads with our Jackass 127H air horn kit. It's designed to give you maximum volume in minimal space. With a mid-range tone that'll make ears perk up, this kit packs a punch that'll even make some train horns jealous.

Featuring the loud and compact Caboose air horn, our Jackass kit is one of the loudest we carry. At just over a foot long, it's the perfect fit for any ride, big or small. And with the 1/4" valve pre-installed, the setup has never been easier.

  • Hassle-Free Installation: This kit includes everything needed from start to finish. With a pre-assembled air source unit, pre-installed fittings, and a horn with a pre-installed air valve, you'll be up and honking in no time.
  • Compact Design, Big Impact: The Jackass 127H kit is meticulously crafted to provide colossal volume in a condensed design, making it versatile for all vehicle sizes and outshining even some of the mightiest train horns.
  • Loudness Beyond Size: Featuring the Caboose air horn, this kit is among the loudest in the HornBlasters' collection, proving that power isn't always about size.
  • Extended Sound Duration: With a max honk time of 6 seconds, not only is the sound intense, but it also lingers, guaranteeing you leave a lasting impression on every passerby.

**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. **
