The Air Lift ALP4 is a pressure-based air management system for air suspension control built around a compact all-in-one anodized billet aluminum manifold that houses the ECU solenoids and pressure sensors. It pairs with a 3.5-inch full-color touchscreen controller with four physical buttons for presets four-corner manual control axle adjustments and full air-out, plus a free mobile app for remote control.
