Expert Reply:
Ultra Fab has stated that usable air pressures can range from 20 to 120 psi. According to Ultra Fab there are many factors that can effect air pressure such as the size of the air spring in diameter and height, the pin weight of the trailer, the mechanics of each individual hitch, altitude and air temperature.
To determine the ride height Ultra Fab has indicated on the lower body of the shock absorber, as shown on the included photo, reference points that should line up with the yellow sticker and arrows. Please note that in order to check this alignment the truck and trailer need to be hooked up, and parked on level ground. When they are hooked up, and the hitch is under load, there should be 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 arrow on the yellow sticker.
