Shocker XL train horns

No, the Shocker S4 is a horns-only product. It includes the four-bell horn, 1/2" stainless steel electric air valve, hoses and fittings, and mounting hardware. You'll need to purchase an air tank and compressor separately, or check out the Conductor's Special kits that include everything in one package.

Yes, the four bells can be mounted individually wherever you have space on your vehicle. This gives you complete flexibility to work around existing components and create a custom installation layout that fits your specific truck configuration.

The four bells range from 12.75" to 19.50" in length, and each produces a distinct tone. When sounded together, these hand-tuned bells create authentic US train horn chords that replicate real locomotive sound. The varying lengths are essential for achieving the authentic train horn performance that's just 1.7 dB different from actual trains.

The Shocker S4 features high-impact ABS construction with stainless steel internals and brass components. This combination delivers durability and weather resistance while keeping the entire system lightweight at just 4.5 lbs for easy installation and flexible mounting options.

Absolutely. The Shocker S4 works great on extended cab trucks. The individually mountable bells give you flexibility to work with the frame layout and existing components. Operating at 150 PSI, the system delivers authentic train horn sound on any vehicle from classic extended cabs to modern crew cabs.
