Frequently Asked Questions

Do these horn kits fit my 2013–2018 Ram 2500/3500?

Yes. Most horns are universal-fit and mount cleanly with included hardware. For the simplest onboard air, choose the Ram-specific kit above for 2014–2018 trucks.

What size air tank should I run?

For quick to moderate blasts, a 2.5-gallon tank works well. For long blasts or triple horns, step up to a 5-gallon tank to maintain volume.

Will an onboard air system help beyond the horn?

Absolutely. Onboard air is great for tire inflation, air tools (brief use), and air-suspension helpers. It’s a versatile upgrade for work and play.

Is installation reversible and clean?

Yes. Universal kits use standard brackets and lines; the Ram-specific onboard air system uses bolt-on mounts for a tidy, no-drill install where noted.

Is it legal to use train horns on the street?

Laws vary by location. Use responsibly and verify local regulations. Many owners reserve horn use for off-road, shows, or emergencies.
