Tom’s Hummer H2 just got an audible upgrade with the addition of our Shocker XL Train Horns — and this setup is as bold as the truck itself. Mounted prominently on the roof rack, these horns don’t just add style — they bring railroad-grade power to the road.

Designed for true train horn enthusiasts, the Shocker XLs are hand-tuned to deliver the authentic tone of a real locomotive. Whether Tom is rolling through the city or parked at a show, his H2 doesn’t just get seen — it gets heard.

Thanks to a stealthy install and premium components, this build proves you can combine clean looks with unmatched sound performance. Massive shoutout to Tom for choosing HornBlasters to take his H2 to the next level.
