ALP4 Air Management, 1/4" Air Line (No Tank, No Compressor)

The ALP4 Air Management System from Air Lift Performance sets a new benchmark for precision air suspension control. Combining advanced hardware with intelligent software, ALP4 delivers faster response, cleaner installation, and expanded customization in one streamlined platform.

At the heart of the system is a compact, all-in-one manifold precision-machined from anodized black billet aluminum. The ECU, solenoids, and pressure sensors are fully integrated into the manifold, reducing wiring complexity and minimizing potential failure points while maintaining a sleek, show-ready appearance.

The system is paired with a premium 5-inch full-color touchscreen controller housed in anodized aluminum. Four tactile physical buttons provide instant access to presets, four-corner manual control, axle-based adjustments, full air-out, and additional customizable functions. With integrated mobile app support, you can monitor, adjust, and fine-tune your suspension from virtually anywhere.
