Chris K. didn’t just upgrade his 2021 GMC Denali, he transformed it into a rolling powerhouse of sound. With the S6 Shocker XL Train Horns paired with our 228H Air System, Chris created a setup that doesn’t just turn heads, it snaps necks!

The S6 delivers that unmistakable deep, locomotive tone, and with six perfectly aligned bells, thanks to the Shocker XL Train Horn Mount and horn extension upgrades, this build looks just as aggressive as it sounds.

From the clean installation to the street-shaking volume, Chris’ Denali is a textbook example of how to do train horns right. Power, precision, and polish all in one.


Key Features:

  • S6 Shocker XL Train Horns – Six-bell configuration for intense, authentic train sound

  • HornBlasters 228H Air System – 2-gallon tank and VIAIR compressor for fast recovery and reliable blasting

  • Shocker XL Train Horn Mount – Clean and aligned six-horn setup

  • Horn Extensions – Perfect alignment for a streamlined, aggressive aesthetic

Train Horn FAQ

No, the Shocker S6 is a horns-only kit that includes the six-bell horn, air line, 1/2" stainless steel electric air valve, and fittings. It does not include an air tank or compressor, which you'll need to purchase separately to operate the horn. Chris paired his S6 horns with the HornBlasters 228H Air System, which features a 2-gallon tank and VIAIR compressor for fast recovery and reliable blasting. Complete train horn kits with the Shocker S6 and full air system are available if you want everything in one package.

Yes, each of the six bells on the Shocker S6 can be mounted individually anywhere on your vehicle. This flexibility allows you to customize your installation based on available space and your specific needs, whether you want to spread them out for optimal sound distribution, keep them grouped together using the Shocker XL Train Horn Mount for a clean aligned setup, or mount them in tight spaces. Chris used the Shocker XL Train Horn Mount and horn extensions for perfect alignment and a streamlined, aggressive aesthetic.

The Shocker S6 features six bells with measurements of 19.50" (two bells), 16.25" (two bells), and 14.75" (two bells) with 5" flares. These different bell lengths work together to create an authentic train horn chord, with each bell producing a distinct tone that harmonizes with the others. This multi-tone configuration delivers the rich, complex sound that replicates real locomotive horns, delivering that unmistakable deep, locomotive tone that turns heads and commands respect on every blast.

The Shocker S6 is constructed from high-impact ABS material, providing excellent durability and weather resistance while maintaining lightweight performance characteristics. This construction ensures the horns can withstand harsh conditions and everyday use, making them perfect for truck installations like the GMC Denali, delivering reliable performance with authentic train horn sound that looks just as aggressive as it sounds.

The Shocker S6 operates at 150 PSI maximum working pressure for optimal performance. This pressure ensures maximum sound output and authentic train horn sound quality from all six bells in the system, delivering that powerful locomotive tone that commands attention from blocks away. When paired with a quality air system like the 228H, you get fast recovery and reliable blasting for show-quality sound and street power.
