Airlift 3H provides 4 corner air spring control through a pressure based system while also using height based sensors allowing the system to re-level when loads change (e.g. adding a passenger).
While Airlift 3H monitors height and pressure, 3P is a pressure only system providing 4 corner air spring control which can be adjusted with both the controller and app.
The former industry standard - Airlift’s ground breaking AutoPilot V2 is the most successful pressure-based digital air suspension control with many features and easy installation.
