The ALP4 Air Management system is a modern, pressure-based air suspension controller designed for clean installs and straightforward, reliable operation. Built around a compact all-in-one manifold, it combines the ECU, solenoids, and pressure sensors into a single unit to reduce complexity and keep everything tidy.
The system includes the ALP4 manifold, controller, wiring harness, and water trap, and can be operated via the controller or the ALP4 mobile app on supported iPhone and Android devices. Presets, manual control, and system monitoring are all handled in a clear, intuitive way, making it easy to dial in your setup and live with it day to day.
This listing is available with 1/4" or 3/8" air line, allowing you to choose the configuration that best suits your build. Both options offer the same core functionality, with the difference coming down to response speed, air volume, and install preference.
The system includes the all-in-one manifold, full-colour touchscreen controller with physical buttons, wiring harness, water trap, fittings, airline cutter, and DOT-rated air line, and offers built-in system diagnostics along with control from the controller or the ALP4 mobile app on supported iPhone and Android devices.
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. Suitable for street cars, show builds, and performance-focused setups alike.
