Description

The Air Lift Performance ALP4 Air Management System redefines air suspension control with a revolutionary blend of cutting-edge technology, precision hardware, and intuitive functionality. Designed for setups using ¼” FNPT ports and ¼” airline, this system is ideal for enthusiasts who already have a tank and compressor and are looking to upgrade to next-level control.

At the heart of the ALP4 system is a compact, all-in-one anodized black billet aluminum manifold that integrates the ECU, solenoids, and advanced pressure sensors into one sleek, durable unit—ready for show or street. The system pairs with a stunning full-color touchscreen controller framed in anodized aluminum and equipped with four tactile physical buttons for quick access to presets, 4-corner manual control, axle adjustments, full air-out, and more.

With Bluetooth-enabled mobile app integration, you can fine-tune your suspension from virtually anywhere. Whether you’re adjusting for daily driving, airing out for a show, or tuning for performance, ALP4 gives you unmatched versatility and control.
