I have a 4 way panel and a one way panel as well. Don't let anyone tell you these are slow, we have used these for years and still do on at least 80% of our installs. If 5 seconds to drop a full size car to the ground from ride height or 8-10 seconds to lift to ride height is slow then I guess these are slow.
You will not find a more practical or economical way to manage an air ride system then these factory assembled and plumbed panels. You will not find a lower price anywhere, if you do let us know and we'll lower ours!
