Helpful Fitment Notes

Compressor duty cycle & CFM: Higher duty cycle and flow refill tanks faster and allow longer horn blasts. If you also want tire fill/airbag use, choose a heavy-duty compressor.
Tank size & pressure: 2–3 gal works for quick blasts; 4–5 gal supports extended use and air tools. 150–200 PSI systems hit harder—verify component ratings match.
Mounting locations: Common spots include the spare-tire area, frame rails, and under-bed crossmembers. Keep trumpets pointed down, protect from debris, and ensure tank drains point downward.
Electrical basics: Run the compressor on a fused relay (30/40A) with appropriate gauge power/ground. Trigger the relay with the pressure switch; control the horn solenoid via a switch or momentary button.
Noise & legality: Train horns may be regulated by local noise ordinances and are typically for off-road/show use. Use responsibly and check your local laws.

Train Horns FAQ – 2019–2024 Ram 2500/3500

What tank size and PSI should I choose?

For horn-only use, 2–3 gallons at 150–200 PSI is common. If you want longer blasts or to air up tires, step to 4–5 gallons and a heavy-duty compressor with a 150/200 PSI switch and matching safety valve.

Where do these mount on a Ram 2500/3500?

Popular spots are the spare-tire well (with a bracket), along the frame rails, or under the bed. Keep trumpets angled down, shield components from road spray, and ensure easy access to the tank drain.

How should I wire the compressor and horn solenoid?

Use a fused relay to power the compressor directly from the battery. Trigger the relay with the pressure switch. Run the horn solenoid on its own switch or momentary button, using proper gauge wire and grounds.

Can the onboard air system also inflate tires or run airbags?

Yes—add a manifold with a quick-disconnect and regulator. Verify compressor CFM/duty cycle supports your use, and include check valves and water separators for reliability.

Are train horns legal on public roads?

Laws vary by location. Many areas restrict extreme-noise devices on public roads. These products are generally intended for off-road/show use—check local regulations and use responsibly.
