Coach on flat ground, at travel ride height:

There are two ride height valves on the rear suspension-- one on each side.

Measure at the air bags in front of the rear tires (toward center of coach).  From above the 1/4" plate above the air bags to below the 1/4" plate below the air bags= 8 1/2"

Lengthening the rod to the ride height valve raises ride height.

Not a good idea to mix immediate response with a standard flow ride height valve especially on the rear axle, KN27000 is standard flow. Immediate response valves work best for our coaches.
