One good blast from our Tug-37 232 air horn kit will cause other drivers to give you a wide berth and ensure smooth sailing when you're out on the road. Bring the sound of the seas to your ride with the loud and low tone of a Tugboat complete with one of our most popular onboard air systems!

While the classic Tugboat sound is already known for having more bass than your average air horn, we wanted to see just how low we could go by extending the bell to 37 inches. The end result is a tone that retains that classic sound while adding some extra rumble and quite a bit more power. While longer than other horns, our Tug-37 air horn’s single back bell can fit into a lot of places can't with its small installation footprint. We pre-plumbed the required 1/4" air valve to make installation even easier.

Our HornAir 232 onboard air system that we paired our Tug-37 air horn with is perfect for anyone wanting their kit to do more than just power horns. Wanting to air up your tires or power some air tools? This kit can handle most pneumatic emergencies that the road can throw at it all while making sure your Tug-37 air horn is always ready to go! The 2-gallon 6-port air tank featured in this kit provides enough air to blast your Tug-37 for up to 4-5 seconds continuously and the fast-filling Viair 380C air compressor will recharge the tank from 110 to 150 in 56 seconds!

Best purchase ever

I wish I would have bought this years ago. Install took some time because of having to make custom brackets but other than that I just smile every time I hit the horn.
