Question:

What is the normal air loss with this air spring? What is the warranty for not holding air on this air spring? This is the problem with the one I have now. It loses 20 psi in 1 day. Thanks

I reached out to the manufacturer, Lippert, who told me the Replacement Air Spring for Trailair 5th Wheel Pin Boxes # LC432404 has a 1-year warranty from the date it was purchased. It should definitely not be losing 20 psi in one day so it sounds like you just have a leak, which may be from the air bag or the inflation valve. You will want to use a solution of soap and water and spray the bag and valve, and wherever the bubbles are forming, you'll know that's where the leak is. The air bag leaking will require a replacement # LC432404 while the inflation valve leaking will need Replacement Pin Box Tank Valve for Lippert or UltraFab TrailAir Pin Boxes # LC156740.
