OUR BIGGEST JACKASS

For those who believe that size isn't always indicative of strength, the Jackass 228H Air Horn Kit is your testament. This compact marvel is a testament to the idea that power can come in small packages. With its three-chime air horn, the Jackass 228H doesn't just make an entrance; it announces its presence with authority, ensuring that every honk is not just heard, but remembered.

While the horn itself belts out a commanding mid-range tone, the accompanying components ensure that the performance is seamless. The HornAir 228H air source unit, paired with the kit, is a symphony of efficiency and power. And with most components being pre-plumbed and pre-wired, the installation is as smooth as the horn is loud.

Effortless Setup: Dive into a hassle-free installation experience with pre-assembled components, including the air source unit, fittings, and a horn equipped with a pre-installed air valve.
Mighty in a Miniature: Don't be deceived by its compact design. The Jackass 228H is a roaring three-chime air horn that ensures you're not just seen but also heard.
Peak Performance: Partnered with the HornAir 228H air source unit, this kit is a beacon of efficiency. The AC-2 air compressor guarantees a swift recovery, and the 2-gallon 6-port air tank ensures you can honk to your heart's content, with up to 8 seconds of honk time.

**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. **
