Incab Air Kit PX03 Tank-Analog kit

An air management system typically includes a compressor, air tank, valves or a valve block, pressure sensors or switches, airlines, a control unit or switches, and in full air setups, height sensors. Together they control how air is delivered to the airbags or struts and how the system maintains or adjusts ride height.

Yes. Any automatic ride-levelling or preset height system requires an air tank so there is enough stored air to raise the vehicle quickly without overworking the compressor. The tank buffers demand and allows smoother, more reliable height changes.

Manual systems use simple paddle valves or switches to control air pressure by feel, and are typically used for Load Assist or basic custom setups. Electronic systems use solenoid valves, height sensors and an ECU to manage presets and maintain ride height automatically. Legal full-air conversions generally require some form of automatic height control.

Regulations typically require that major ride-height changes do not occur while the vehicle is in motion. Electronic air management systems usually monitor handbrake or vehicle speed and only allow height changes when stationary or below a defined speed, to maintain safety and stability.

The kit comes with a 1-gallon aluminium air tank. This size is ideal for providing sufficient air supply for Load Assist operations while remaining compact for easy installation.

While the PX03 kit is primarily designed for standard height and up to 2-inch lift applications, it can be adapted for higher lifts by using appropriate fittings and configurations. Always consult with Boss for specific recommendations based on your vehicle's setup.

The included 110-135psi pressure switch automatically regulates the air pressure within the system, ensuring that the airbags maintain the desired pressure for optimal performance. This helps prevent over-inflation and maintains consistent handling.

This kit is commonly used in vehicles that require Load Assist for towing or carrying heavy loads. It is particularly beneficial for maintaining vehicle level and stability when loaded, and for adjusting airbag pressure on-the-fly while driving.

The aluminium air tank included in this kit will not rust internally like steel tanks, ensuring a longer lifespan and consistent performance. Regular draining is still recommended to remove moisture from the system.
