Full Air Ride System for 1973–1987 C10/C20/C30

Getting your squarebody sitting just right starts with the right setup. This AccuAir VU4 3/8 Air Ride Kit is designed for 1973–1987 Chevy/GMC C10, C20, and C30 2WD trucks, delivering smooth ride quality, responsive control, and a clean installation using proven components that work together seamlessly.

At the core of the system is the AccuAir VU4 manifold, which reduces plumbing complexity while maintaining accurate 4-corner control. Matched with dual airmaxxx 580 black compressors and a 5-gallon tank, this setup provides steady air supply and consistent performance for both daily driving and show builds.
