Shocker XL Train Horns

No, the Shocker XL train horn (part number AH-S4) is a standalone horn set and does not include an air system. You will need an air tank, compressor, pressure switch, air valve, hoses and fittings, and wiring to power the horns, whether you build a custom onboard air setup or use a complete kit. Chris’s 2022 Ram 2500 installation shows how Shocker XL horns can be paired with a capable air system to deliver authentic train horn sound while keeping the components tucked neatly on the truck.

Yes, the four Shocker XL bells can be mounted separately to work around the space available on your 2022 Ram 2500. The bells come in four different lengths, allowing you to stagger them along frame rails, crossmembers, or behind bumpers while still tying into a single air inlet. This flexibility makes it easy to create a clean, tucked install that fits your suspension, exhaust, and off-road accessories without sacrificing sound.

The bells on the Shocker XL are different lengths to create the authentic multi-tone chord you hear from real US locomotives. Each bell produces a slightly different pitch, and when they fire together you get that powerful, realistic train horn sound that turns heads and demands attention. On a full-size truck like Chris’s 2022 Ram 2500, that chord really stands out whether you are cruising the streets or hitting the trails.

The Shocker XL train horn is made in the USA from high-impact fiberglass-reinforced ABS with stainless steel and brass hardware for durability. This combination keeps the bells lightweight for easier mounting while still standing up to road grime, weather, and the pressures of an onboard air system. It is a great match for a 2022 Ram 2500 that sees daily driving, towing, or trail use where you want strong, reliable horns that will last.

The Shocker XL train horn uses a ⅛-inch M NPT fitting and requires a 1/2-inch port for proper air flow. This standard connection makes it easy to pair the horns with most onboard air systems designed for train horns, including 2-gallon and larger tanks. As long as your air system can supply adequate pressure and flow through a 1/2-inch port, you can achieve the same authentic locomotive sound Chris gets from his 2022 Ram 2500 setup.
