Air Ride Setup for 1988–1998 Silverado / Sierra 1500

A lowered OBS truck should ride just as good as it looks. This AccuAir VU4 3/8 Air Ride Kit is built for 1988–1998 Chevy Silverado and GMC Sierra 1500 2WD, delivering smooth ride quality, responsive control, and a clean installation using proven components.

At the core of the system is the AccuAir VU4 manifold, designed to simplify plumbing while maintaining accurate 4-corner control. Paired with dual airmaxxx 580 black compressors and a 5-gallon tank, this setup provides consistent air supply and reliable performance for both daily driving and custom builds.
