ALP4 is Air Lift Performance’s most advanced air suspension management system yet, with a new user-friendly design.

The free ALP4 mobile app features improved connectivity and a user-friendly interface, based on the full-color touchscreen controller, letting you take control of your presets, axle adjustments, or full air-out.

ALP4 has been completely redesigned, with more responsive timing. The app is completely customizable and can be set to match the colors of your system’s remote.

For complete control of your ALP4 air compressor system, our app allows you to manage your system, even when the remote isn’t handy or you’re trying to showcase what your vehicle can do.

For those upgrading from a 3P/3H system, ALP4 represents a significant leap forward, completely rethinking air suspension management, built for trailblazers ready to shape the next generation of performance.
