Pressure vs Height-Based Air Suspension Management

Pressure-based management uses air pressure targets. Height-based management uses suspension position sensors. Each approach has its own setup requirements and tradeoffs.

What pressure presets do

A saved pressure target provides a convenient starting point. It does not directly measure vehicle height. The height at that pressure can change with passengers, cargo, geometry or other setup changes.

What height sensors add

Sensors measure position in the suspension’s travel. They require suitable mounting, calibration and an installation compatible with the chosen system. Do not assume that every ONAIR management product supports adding height sensors.

Choose the control layout

2V focuses on front/rear control; 4V and AirBoy offer individual four-corner control. Check the current product specifications for sensor support, presets and display information.

Set and recheck the car

Establish a usable driving height, have alignment checked and verify clearance under the loads you actually carry. Contact ONAIR about your requirements instead of assuming pressure automatically compensates for every load change.
