Hear these horns now!


The Conductor's Special 248 packs a huge train horn sound, all while using very minimal installation space! Our Conductor’s Special 248 train horn kit is designed to be compact and budget-friendly, as well as pack enough punch to get the attention of everyone around.  The Conductor’s Special 248 train horn kit is universal and has been installed on everything from ATV’s too big rigs.

Our shocker XL train horns that come with the Conductor’s Special 248 train horn kits are some of the loudest horns you can buy, giving you the tone and intensity of a real train horn without having to spend thousands. As four separate bells, our Shocker XL train horns are perfect for tight install spaces and when coupled with our HornAir 232 onboard air system, makes for a train horn kit that you can install almost anywhere on anything.

With our weather-resistant 2-gallon tank and Viair’s 480C air compressor, you get a complete system that is capable of providing a 5-7 second blast time and refilling in less than 2 minutes! This air system is also capable of being used for airing up tires or using an air tool if needed. The Viair 480C air compressor is a constant duty air compressor. Making this the perfect unit for those other pneumatic uses as well as honking the horn. Everything is included along with detailed instructions, making installation easy enough for anyone to be able to do. 

Please note: The 6 horn upgrade kit does NOT include the extension brackets to connect to our STDK bracket or Shocker XL horn mount.

Blow it and keep on blowing it

I love this kit. Not only is it loud AF but it scares the **** out of people and that’s the funniest part. However besides the fun aspect, it has saved me from so many different accidents and lots of headache from idiot drivers. And it really wakes up people when they aren’t paying attention to how their driving.

While cruising around I heard someone blow there horns, and I was like I have to have them. So I get online and order some horns. Put them on not loud enough, order from another company still not loud enough. I finally asked the other guy where they came from he tells me horn blasters. So I find the site go through many different sounding amazing horns. Finally get my pic. The shipping was extremely fast. Got these put on. Kids were playing basketball when I blew them the first time, mt son completely missed the whole goal. I finally had the horns I've been looking for. Everywhere you go when you sound these things off, every head turns smiles everywhere. Some of the people completely lose whatever they where holding. I love them would recommend hornblasters to everyone, and will definitely do business with again. AAA+++

WOW what a setup for the money!

The kit arrived fast and came with everything I needed to install it. I was able to get it installed on my 2013 Ford f-250 in just a few hours. My first drive out with the horn some teenager texting and driving made his way into my lane....... let's just say his phone ended up in the back seat after I blasted these horns. Overall a great product and great service from the team at hornblasters.
