The ALP4 pressure-based 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. The manifold’s customizable LED-lit top cover lets builders match their system’s color to their vehicle. ALP4 offers multiple preset ride pressures and full manual control, allowing for instant air-outs and show-ready configurations. 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, or full air-out. With mobile app integration, ALP4 allows you to use and fine-tune your setup from anywhere, ensuring ultimate control. ALP4 can be run as a height-based air management by simply incorporating our Height Upgrade Kit. Designed for plug-and-play installation, the ALP4 harness reduces wiring complexity, requiring only power, ground, and keyed ignition, thereby eliminating the guesswork common in air suspension installations. Plus, built-in diagnostics with user-friendly messaging ensure real-time system feedback, giving drivers the confidence to hit the road or the show floor without surprises.
