Thanks guys,



I was going to replace the valves as well as adjusting my tag axle
pressure down to 60 psi from it's current 72 psi. Steer axle has too much
weight on it and the tag is too light. My coach has always looked a
little nose heavy, after checking the prescribed measurements it is nose
low. Weighed the coach and she is within 180 lbs of max steer axle weight
and the tag has an extra 1100 lbs to take up some of that weight.



Just to make sure I get the correct part.
