Why This Kit Stands Out
This ALP4 Squarebody air ride system combines dependable digital air management with quality airmaxxx suspension components for a clean and reliable setup. The integrated manifold helps reduce plumbing clutter while the programmable presets make it easy to switch between comfortable driving height and aggressive show stance.
Whether you're building a lowered cruiser, custom show truck, or daily-driven Squarebody, this package delivers responsive suspension control, smooth ride quality, and modern convenience in one complete system.
