    Thanks for finding that. But not all Z71 are equipped with adaptive air. And it’s not clear if this particular one was. Although, there has been an early assembly hiccup where some air lines were not properly seated.

    It’s a pretty interesting system when you read this internal GM briefing. Give it a read. You might be surprised.

    The user stated it was air-ride equipped. I've actually seen that article before, and it's nothing new. Ask any service department... they're nothing but trouble.
