High-Speed 1/2" Air Ride Setup for GM B-Body Cars

Built for fast action and aggressive suspension movement, the airmaxxx 1/2" Fast Bag Air Ride Kit gives your 1971–1996 GM B-Body the airflow and response needed for hard drops, rapid lift, and serious stance control.

This high-flow 200 PSI air suspension package uses oversized 1/2" valves, fittings, and airlines to move air much quicker than traditional 3/8" systems. Whether you're building a slammed Caprice, custom Impala, or full-size Buick cruiser, this setup delivers strong performance with dependable components designed for daily use or show duty.

The included AVS manual 7-switch controller gives you direct hands-on control of all four corners without relying on complicated electronics or ride height sensors.
