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. If you need everything to get started, check out our Conductor's Special train horn kits which include the Shocker XL horns plus a complete air system.

Yes, the four Shocker XL bells can be mounted separately to work around the space available on your vehicle. The bells come in four different lengths (19.50", 16.25", 14.75", and 12.75"), 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 other accessories.

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. The precision-tuned sound replicates US train horn chords with an impressively minimal loudness difference from the real thing.

The Shocker XL train horn is made in the USA from high-impact fiberglass-reinforced ABS with stainless steel internals and brass fittings. This combination keeps the bells lightweight (4.5 lbs total) for easier mounting while still standing up to road grime, weather, and the pressures of an onboard air system. The robust American craftsmanship ensures durability and longevity for reliable performance.

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. The system operates at up to 150 PSI maximum working pressure, so as long as your air system can supply adequate pressure and flow through a 1/2-inch port, you can achieve authentic locomotive sound.
