3H Air Management System

Height + Pressure Control
Air Line Options: 1/4" or 3/8"
No Tank, No Compressor

The 3H Air Management system combines height-based and pressure-based control in one setup, giving you consistent ride height with the option to fine-tune pressures when needed. Using ride height sensors at each corner, the system automatically returns the car to preset heights regardless of load or road conditions.

The kit includes the 3H manifold, controller, wiring harness, water trap, and height sensors, and can be operated via the controller or the mobile app on supported iPhone and Android devices. Once set up, the system manages itself quietly in the background, keeping the car where it’s meant to be without constant adjustment.

This listing is available with 1/4" or 3/8" air line, allowing you to choose the configuration that best suits your build, install space, and response preference.

Compatibility and use:
Designed for vehicles running an existing air tank and compressor, or for custom air suspension builds. Compatible with standard air suspension layouts and commonly used with Air Lift air bags, as well as other aftermarket air suspension brands that use industry-standard fittings. Well suited to daily-driven cars, long-distance setups, and builds where consistent ride height matters.
