You can never have too much onboard air! More air means longer blast time for your horns, more air for your tires, airbags & power tools. With our Conductor’s Special 8OB2 fast-fill train horn kit, you get all the air you could ever need and then some. With 8 gallons of air being powered by dual Air Zenith OB2 air compressors, you never need to worry about not having enough air to get the job done again. With this kit, you can unleash a whopping 20 seconds of honk time that can be heard for miles! 

The 8OB2 kit was designed for use with our Shocker XL train horns to bring you the full power and tone of an actual locomotive.

We also stand behind them with a lifetime warranty against manufacturer defects. Our Conductor’s Special 8OB2 fast-fill train horn kit gives you one of the loudest, most reliable, and easy to install train horns you can buy.

The powerhouse that fills the massive 8-gallon, 8-port tank is a set of dual Air Zenith OB2 air compressors. This comes together to give you a system that's capable of blasting your Shocker XL train horn for 20 seconds and recovers your 8-gallon tank in a blazing 40 seconds! Let that sink in for a minute.
