Air Lift – ALP4 Pressure-Based Air Management System 3/8 in (No Tank, No Compressor) – Universal – 27485

The Air Lift ALP4 Air Management System (27485) represents the next evolution in air suspension control, combining advanced hardware, intelligent software, and a refined user interface into a compact, all-in-one solution. This pressure-based system features a billet aluminum manifold that integrates the ECU, solenoids, and pressure sensors internally—delivering cleaner installs, fewer failure points, and a show-ready appearance.

At the center of the system is a 5-inch full-color touchscreen controller housed in anodized aluminum and equipped with four tactile physical buttons. Users gain instant access to presets, 4-corner manual control, axle adjustments, full air-out, and other customizable functions. With mobile app integration, ALP4 allows you to monitor and fine-tune your air suspension setup from virtually anywhere.

This configuration includes 3/8-inch DOT air line, making it ideal for higher airflow applications while remaining fully compatible with threaded 1/4-inch FNPT manifold ports. The ALP4 is also upgradeable to height-based control using Air Lift’s Height Upgrade Kit and integrates seamlessly with optional tank and compressor kits (sold separately).
