Recommended Air Pressure on Lippert TrailAir Ride 5th Wheel King Pin
Updated 05/22/2013 | Published 05/20/2013
Question:
What is the proper air pressure to put in the air bag?
asked by: Rich
Expert Reply:
According to Lippert 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. Lippert has stated that air pressures can range from 20 to 120 psi. Therefore a specific air pressure is not recommended. Instead a ride height is recommended to be maintained.
To determine the ride height Lippert has indicated on the lower body of the shock absorber, as indicated on the included photo, should line up with the yellow sticker and arrows. Please note to check this alignment the truck and trailer need to be hooked up, parked, and 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.
