Understand the control method

Pressure and height are different signals.

Air Lift 3P is pressure-based; 3H adds height sensing. These are specific product examples, not a description of every management system. Confirm the exact generation, hardware and supported upgrade path.

Identify the supporting pieces

Air supply is separate from the struts.

Compressor

Produces the air supply. Check pressure capability, duty cycle, electrical requirements and mounting.

Tank

Stores the compressed air. Check capacity, rated pressure, ports, drain access and secure mounting.

These photos illustrate different component roles. They are not a preselected compatible system.

Installation & upkeep

Set a driving height. Maintain the system.

Follow the exact installation and calibration instructions, leak-test connections and inspect routing through the full permitted suspension travel. Use a driving height with adequate clearance and travel. Parked display settings may be unsuitable for driving.

Service moisture handling and tank drainage as directed, check fittings and mounts, and maintain the compressor and filters on the manufacturer’s schedule. Repeated compressor operation can signal a leak or another problem; diagnose it rather than raising limits.

Align at the approved driving height and normal load. Confirm any manufacturer minimum/maximum pressure and height limits; there is no universal pressure recommendation for every air spring.
