GET ALL HONKED UP WITH THE CONDUCTOR'S SPECIAL FAST-FILL OB2 KIT. 

Designed for the person that loves to blow their horn for an outrageous amount of time, our Conductor’s Special fast-fill 5OB2 train horn kit gives you all the air you would ever need to blast your heart out! It's also one of the fastest recharging kits we sell.

The Conductor's Special OB2 utilizes our Shocker XL train horns to bring you the full power and tone of an actual locomotive. Our horns are constructed from an ultra-durable fiberglass-reinforced ABS composite and our diaphragms are made from stainless steel. We also stand behind them with a lifetime warranty against manufacturer defects. Our Conductor’s Special OB2 train horn kit gives you one of the loudest, most reliable, and easy to install train horns you can buy.

Taking center stage in this kit is our HornAir OB2 Onboard Air system. Providing you the ability to choose between our 2-gallon air tank, 5-gallon air tank, and our 8-gallon air tank. With our 2-gallon air tank, you will get about 3-4 seconds of honk time. With the 5-gallon air tank, you will get roughly 8-10 seconds. And the 8-gallon tank will provide about 13-16 seconds. Using the 5-gallon tank or the 8-gallon tank will provide enough capacity to give you plenty of onboard air in case of a road emergency that requires you to inflate a tire or to use for air tools for example. Our Conductor’s Special OB2 fast-fill train horn kit features one of the fastest compressors available, the Air Zenith OB2. Ensuring you always have air when you need it.

Please note: The 6 horn upgrade kit does NOT include the extension brackets to connect to our Shocker XL horn mount.
