Upgrade your existing Air Lift Performance air management system to the next generation of suspension control with the ALP4 Upgrade Kit. Designed as a direct upgrade for Air Lift Performance 3P and 3H air management systems, this kit delivers the advanced features, refined performance, and modern functionality of ALP4 without replacing your entire setup. At the heart of the system is the compact all-in-one ALP4 manifold, which houses the ECU, solenoids, and pressure sensors in a durable anodized billet aluminum body. This streamlined design reduces installation complexity while delivering faster, more accurate system response and improved reliability. ALP4 introduces advanced ride adjustment algorithms with road filtering and adaptive learning, resulting in more accurate pressure control and eliminating unwanted adjustments after braking or long turns. Drivers can take advantage of multiple preset ride pressures, manual four-corner control, axle adjustments, and instant air-out functionality. With its cleaner install, smarter control algorithms, and enhanced connectivity, the ALP4 Upgrade Kit brings the latest evolution of Air Lift Performance air management technology to existing systems.
