Air Lift Performance ALP4 Management System For Use w/ 1/4" Air Line

The ALP4 Air Management System sets a new standard for air suspension control, blending advanced hardware with intelligent, user-friendly functionality. At its core is a compact, all-in-one manifold—housing the ECU, solenoids, and pressure sensors—precision-machined from anodized black billet aluminum for long-lasting durability and a premium, show-quality finish.

Control is effortless with the full-color touchscreen controller, framed in matching anodized aluminum and complemented by four tactile buttons for quick access to presets, manual 4-corner control, axle adjustments, full air-out, and more. For added versatility, ALP4 includes mobile app integration, letting you monitor and fine-tune your system from virtually anywhere.
