Hear these horns now!

Looking for the loudest air horn that we make? As the two smallest out of the four notes from the Shocker XL Train Horns, our Rocker Air Horns are technically classified as an air horn, since they only form half of a full train horn chord. Don’t let that fool you into thinking they are your average air horn, though. With a similar tone and volume as their 4-bell big brother, our Rocker Air Horns are the loudest and one of the deepest air horns available.

As two individual horns made of super light and ridiculously durable fiberglass-reinforced ABS composite, our Rocker Air Horns are one of the easiest horns to install in cramped spaces. Wanting to get a train horn sound for your motorcycle or ATV? These are the best air horns to go with. Everyone always suspects the big truck to have a bighorn, but the look you will get from setting them off on a smaller vehicle is priceless!

The best thing about our Rocker Air Horns is they are easily upgradeable. If you are like us, two horns will only satisfy you for so long. With our Rocker Air Horns, you can easily move up to our 4-bell Shocker XL Train Horn with our Rocker to Shocker Horn Upgrade Kit!

I installed these in a 2013 dodge Avenger with a 5 gallon tank in trunk with 190 psi. SUPER LOUD on the car.

Just buy it

Awesome company , customer support and superior products. I own a collision shop in NY and sell truck accessories and spray bedliners for over 30 years. I use to be a Hadley fan but no more. HORNBLASTERS literally BLOWS THE COMPETITION AWAY. You will not be disappointed.


Horn blasters rock.

I coupled the rocker horn kit with the existing Jack *** system. Man, what a sound. I believe I will have hearing loss as a old man. But, well worth the fun
