How much air does it take?

Combination of things affect the amount of air needed such as; the size of the air spring in diameter and height, the pin weight of the coach, the mechanics of the individual hitch, altitude and ambient temperature. Air pressures can range from 20 psi to 120 psi depending on the aforementioned items. The air ride pin box is to be maintained at a predetermined ride height found on the system. We want you to maintain the ride height, not the air pressure. With the truck and trailer coupled, at rest and on level ground, you should have enough air in the bag to open the jaw to a point that the bottom lip of the top shroud on the shock absorber is even with the arrows on the decal that is affixed to the lower body of the shock absorber.
