Why Buy Train Horn Gear from CPP Diesel?

Curated for 03–07 Ram: Universal components that mount cleanly on 3rd gen frames, beds, or behind bumpers.
Reliable duty cycles: Compressors and tanks sized to keep blasts consistent without overheating.
Straightforward installs: Kits and accessories that simplify wiring, plumbing, and mounting.

Tech Notes & Fitment Tips

Tank sizing: 0.5–1.0 gal works for short chirps; 2.5–5 gal supports longer blasts and faster recovery.
Compressor choice: For frequent use, pick a continuous-duty 12V unit (HP625/HP325 families) and mount away from heat.
Plumbing: Use quality push-lock or braided line, add a drain for condensation, and secure lines away from the driveline/exhaust.
Electrical: Trigger horns with a fused relay and a dedicated switch or remote; follow the product’s amp draw specs.
Legal use: Train horns can be off-road/show use only in some areas—know and follow your local laws.

Frequently Asked Questions

What size air tank should I run?

For the loudest, sustained blasts, go 2.5–5 gallons (see HP10050 2.5 gal, HP10051 5 gal, or Viair 91028).

Do I need a continuous-duty compressor?

Yes if you plan to use the horn often. Choose a 12V unit like HP10628 HP625 or HP10142 HP325 for reliable recovery between blasts.

Where do these horns mount on a 3rd gen?

Popular locations include under-bed crossmembers, behind the front bumper, or along frame rails. Keep trumpets pointed down to shed water, and mount tanks/compressors away from heat and road debris.

Can I tie my horn button into the factory horn?

Most builders use a dedicated push button or remote (Kleinn 320, Kleinn 333) via a relay so the OEM horn still works normally.
