    Need to replace the height control valve on my 09 389. It has low air leaf, is it still 8.5” on a 389? Thanks in advance

    If you're replacing just the valve and not the rod and using the exact replacement part from Pete I dont see why the ride height will change. But Mr. @pushbroom can tell ya the ride height if you post up the last 6 of your VIN.

    The valve bolts to slotted holes, have to re adjust when replacing. The old valve was out of whack and was compensated for as well so cant just mark holes and put in same spot. Last 6 of vin are 784758
