Air Ride Setup for 1978–1988 GM G-Body

Getting your G-Body to sit right and ride smooth starts with the right components. This AccuAir VU4 3/8 Air Ride Kit is designed for 1978–1988 GM G-Body cars, delivering responsive control, consistent air performance, and a clean installation for builds that demand both function and style.

Built around the AccuAir VU4 manifold, this system simplifies plumbing while maintaining accurate 4-corner control. Combined with dual airmaxxx 580 black compressors and a 5-gallon tank, it provides reliable air supply and smooth operation whether you're cruising or dialing in your stance at a show.
