I just replaced two of the three valves on my Spartan Chassis. I have three valves with two in the rear controlling the side to side leveling and the one in the front the fore and aft leveling. I was going to replace the front also but foung the linkage was out of adjustment. My coach now has working air suspension now and I am a lot happier to have everything working.
