I went with the Airlift Wireless Air to avoid having to run air lines into the cab. I did have a failure of the controller/manifold but it was replaced painlessly under warranty and no issues since. One big advantage is it automatically maintains the pressure setting or the minimum 5 psi. Another advantage is I can walk around the vehicle with the controller in hand and adjust the air while watching the springs. I like to inflate the bags until the springs lift off the overloads then lower the pressure until they just engage. That seems to work best for keeping the side to side rocking at a minimum. They now have
multiple wireless options.
