Our new HornBlasters Shocker S6 544K nightmare edition 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 train 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 train 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 444C 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!

  • Extremely durable & loud!
  • Industrial grade stainless steel diaphragms
  • Extra-large 5-gallon air tank
  • Capable of Filling Tires
  • All-inclusive train horn solution!
  • All standard mounting hardware
  • Max honk time: 8-10 seconds

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.

Definitely a crowd pleaser

Install time was limited so quickly set up the horns in my truck cap. Will eventually do a more permanent install down the road. What better way to get a crowd cheering then with Horn Blasters

HornBlasters Shocker S6 544K Nightmare Edition Train Horn Kit Review

Absolutely love it

These horns or ungodly loud scared me the first time I hit them. Easy to install worth every penny.



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 !!!
