The 847 Wolo will give any truck 12-volt the powerful sound of a train air horn.
Engineered with the latest technology, the Siberian Express uses reinforced ABS.
The incredible sound produced by the three trumpets is impressive.
The overall weight is decreased by using reinforced ABS, making installation easier and resulting in less vibration when driving on rough roads.
Operated by a heavy-duty electric solenoid valve, the horns are included.
Finished with an attractive semi-gloss black finish, the trumpets and the horns’ base is painted steel.
All mounting hardware, 10 feet of 1/4” nylon high-pressure hose, and a heavy-duty electric solenoid valve come with the horn.
An on-board air system is required for the Siberian Express (recommended Wolo on-board air system is Model 840).
