Product Description

Our legendary Shocker XL Train Horns are by far our most popular train horns and a staple in our famous Conductors Special Train Horn Kits for good reason: the Shocker XL Train Horns are hands down the best bang for your buck. Hand-tuned to the exact specifications of the US Train Horn Chord, our Shocker XL Train Horns not only sound just like the real deal, but they are just as loud. With only a difference of 1.7 dB between our Shocker XL Train Horn and the high-end real locomotive horns like the Nathan Airchimes, you get the sound of a real locomotive at only a fraction of the cost.

While the sound of our Shocker XL Train Horns is that classic train horn tone, the design is anything but ordinary. Made here in the US, our Shocker XL Train Horns are constructed from the most durable automotive materials available including heavy-duty fiberglass reinforced ABS plastic, stainless steel, and brass. While the fact that they aren’t huge metal horns may some the wonder about the sound or durability, these horns are some of the toughest horns we sell, and the only ones we back with a lifetime manufactures defect warranty and honestly, their sound puts other huge metal horns to shame.

Not only do our Shocker XL Train Horns give you a massive sound for a low cost, but they are also the easiest horns to install. The fact that the four individually mounted bells are super light and compact means you can install them just about anywhere. Seriously, we have seen customers install them in wheel wells, front grills, motorcycles, golf carts, backpacks, the list goes on.

Bottom line: As far as matching decibel for dollar, our Shocker XL Train Horns cannot be beaten. You won’t find a horn that is louder without spending a fortune on authentic train horns, let alone ones that have the same ease of install that is backed by a lifetime warranty. Don’t take our word for it though, their ridiculously loud tone speaks for themselves.

Our Shocker Train Horn can also be easily upgraded to include a stainless steel valve or upgraded to our Shocker S6 Train Horn with our Shocker XL 6 Horn Upgrade Kit to give the loudest train horn we make even more power and presence!
