Q: Where does the A1 On Board Air System mount?
You’d normally:
- Mount the tyre valves near/on the rear of the vehicle.
- Mount the compressor under the bonnet or in the cabin area.
- The gauge and dump buttons are best in the cabin where they can be seen by the driver.

A: Yes, they allow for vehicles that may have a heavier load on one side, such as:
- Toolbox on a ute
- Water tank/fuel load on one side of a 4WD vehicle.
