Air Lift Performance ALP4 Air Management

The Air Lift ALP4 Air Management System redefines what’s possible for air suspension control, combining cutting-edge hardware with smarter, more seamless functionality. This system features a compact, all-in-one manifold, which houses the ECU, solenoids, and pressure sensors, crafted from anodized black billet aluminum for durability and a sleek, show-ready appearance. Paired with a full-color touchscreen controller framed in anodized aluminum and equipped with four tactile physical buttons, this system offers immediate control for your presets, 4-corner manual control, axle adjustments, full air-out and other adjustable functions. With mobile app integration, ALP4 allows you to use and fine-tune your setup from anywhere, ensuring ultimate control.

ALP4 is sold without tank and compressor; however, several Tank + Compressor + Hardware kits are available to pair with ALP4 for a complete system solution.
