Shocker S4 XL, Train Horn

The Shocker horns are the loudest, most reliable train horns in their class! These horns are crafted from fiberglass reinforced ABS plastic with stainless steel diaphragms that will not rust. They not only have a genuine train horn sound, but sound at 148db at just 100 PSI. The lack of a shared manifold makes these horns capable of being installed separately, so installation is a breeze on any size vehicle. This product includes the four Shocker horns, an electric air valve, airline, brass fittings and mounting hardware.

These locomotive train air horns are constructed from the most durable automotive materials available including heavy duty fiberglass reinforced ABS plastic, stainless steel, and brass. These horns are crafted to meet rigorous standards in the USA. The diaphragms are stainless steel and will never rust!

They are built rugged, compact, and lightweight and are the perfect fit for any project. If that wasn't enough their size is much smaller than you'd expect. With the longest horn being roughly 20 inches long and the bells only 5 inches in diameter these horns can be mounted just about anywhere. Unlike other horns these horns can be mounted separately since they do not share a manifold. Use your imagination and this can provide for some promising applications!
