The Conductor’s Special 127H Train Horn Kit is built around our Shocker XL horns for a true locomotive tone with extreme loudness. Four individually mounted bells give you flexible placement on cars, trucks, and SUVs, so you can route each bell where it fits best and keep the pitch and presence you want.
This system pairs a 1.5-gallon tank at 120 PSI with our 2L compressor for a reliable air system with fast recovery. Expect a 2–3 second honk per fill with quick recovery between honks. Stainless steel internals and fiberglass-reinforced ABS bells handle weather, road grime, and daily use with ease.
This is a complete kit with everything needed for install: Shocker XL horns, 1.5-gallon tank, 2L compressor, pressure switch, 12-volt air valve (solenoid), air line, push-to-connect (PTC) fittings, wiring, and mounting hardware. The same air system can also inflate tires and run small air tools when needed.
Place each bell where it fits best—along the frame rails, in the bumpers, behind the grille, or in the spare tire location. Independent mounting preserves the four-note spread and forward projection, giving you placement flexibility without sacrificing tone or volume.
Shocker XL horns produce a true locomotive, four-note chord. Voicing and bell geometry deliver the deep tone people expect from a train horn, with the output to cut through traffic and highway noise. When you honk, people hear it.
120 PSI system with about 2–3 seconds of honk per fill and quick recovery between honks. The tank is powder-coated for corrosion resistance, and the system uses push-to-connect (PTC) fittings for clean plumbing. Stainless hardware and a 12-volt air valve (solenoid) keep the setup reliable for daily use.
Use the same air system to air up tires and power small air tools when needed—handy after off-road trips, towing, or seasonal changes. Add a standard air hose and chuck or blow gun (sold separately) and you’re set.
