Hear these horns now!

Our new HornBlasters 544 Nightmare Edition Shocker S6 544K Train Horn Kit gives you more of what you want in a train horn kit. More air, more performance, and (more importantly) more volume! Featuring six of our legendary Shocker XL Train Horn bells, you get the full force and power of an authentic train horn and then some. On top of that, you get one of our most powerful onboard air systems that not only powers these ridiculously loud horns, but can also be used for tire inflation, air tools, air suspension, and more!

Our Shocker S6 Train Horns included with our Shocker S6 544K Train Horn Kit are some of the loudest horns we carry. Made in the US and hand-tuned to the official US Train Horn Chord, our Shocker S6 horns are the closest you can to the tone and volume of an authentic locomotive without spending thousands on the real thing. In addition to the four standard bells that come with our Conductor’s Special Kits, our Shocker S6 544K Train Horn Kit comes with an extra #2 and #3 bell to boost the volume and give you the loudest Shocker Kit that we have to offer.

What better system to pair our Shocker S6 horns with than our HornAir 544 Onboard Air System? With our massive 5-gallon tank you can get up to 4 continuous ear-splitting seconds of blast time with your Shocker S6 Train Horns. The Viair 444K Stealth Black Air Compressor is well known for its power and reliability. With a 100% duty cycle at 100 PSI, our Shocker S6 544K Train Horn Kit is more than ready to tackle almost any pneumatic task the road can throw at it. With a recharge time of 3 minutes from 110 to 150 PSI, you will have your air ready to go when you need it!

Still not enough power for you? Select the Dual Compressor option in the drop-down menu to double your power with a second Viair 444K Stealth Black Air Compressor, cutting your recharge time down to 1 minute and 35 seconds from 110-150 PSI.


This video shows our Shocker XL Train Horn in a third-party decibel test alongside your typical "air horn" honked side-by-side at the same pressure. As you can see, no one even comes close to the insane volume and tone of our Shocker XL Train Horns!

This is a great set of train horns! The kit comes with all the fittings, wiring, and air line needed to install the horns on your truck. The S6 kit offer 6 trumpets, and are some of the loudest set of horns I've heard. The included instructions make this kit very easy to install.



Love this set up !!! It is LOUD !!!


Shocker s6 Nightmare

I am super stoked about my train horn setup, super loud and having fun with them


2000 Tacoma Approved ��ӕ��

I save up for a while to buy this kit and I definitely don't regret it one bit! It took a while to install due to some fabrication I had to do but definitely worth it. Once I finished I fired up the compressor and let them horns rip! Instantly ****** off my neighbors but I don't regret it. Extremely loud and obnoxious. A definite must have for anyone who wants a train horn but doesn't want to pay 3K


Obnoxiously Loud !!!

2 days for delivery. What!? Awesome. It took me 48 days to complete the installation 'cause I knew it was going to be permanent. I welded a bracket to mount all 6 horns to then welded the bracket to the spare tire well & cut the 5/16" hoses as short as possible. All wires are ran through split loom tubing. I fabed a bracket (basket) to the steel bed rails to keep it off the bed then mounted my aluminum tool chest to it then installed both compressors and tank in the chest to keep them away from the elements. The compressors are fairly loud as they vibrate the flimsy walls of the tool chest but serve their purpose. This setup of the Shocker S6 544 Nightmare Edition is insane to be put mildly. I never thought a train horn could be this loud.. When I'm driving on I-70 with any cars around me, the second I sound these horns, the cars around me scatter like they're running away from TWD. It's so hilarious! The crew at HornBlasters are the apiffany of creators/builders of masterful horn loudness. 2 _�ԍ'S up. I am definitely addicted to these horns Thank you HornBlasters!
