The Airmaxxx 3/8" X4 Air Management Kit provides complete 4-corner air ride control, built for seamless installation and powerful performance in custom air suspension setups. It features independent 4-corner control, allowing you to adjust each wheel individually for maximum stance flexibility. The dual compressors deliver 180 PSI power, which is strong enough to handle heavy builds with ease. The kit includes a manifold with dedicated gauge ports for analog or digital meters, simplifying monitoring. This comprehensive kit comes with dual 3-gallon air tanks, the airmaxxx X4 3/8" 4-corner manifold (AM-AVX4-38H), and the X7 handheld switch box (AM-X7R) for intuitive control. Installation is simplified with plug-and-play convenience, featuring a 9 ft extension harness (AM-WK-3P2) and a full dual compressor wire kit (AM-WK2). It also includes nickel-plated brass Camozzi fittings, element filters for the tanks, two 3/8" water traps (AM-WT38-BK), 50 ft of 3/8" DOT-approved airline, a hose cutter, and airmaxxx sealer, ensuring durable components and long-lasting reliability. The fitment information indicates a universal fit for custom air ride suspension systems. It is also compatible with DTC Frame Mounts from Velaworks, offering added versatility for specific applications.
