Does Air Pressure in Trailair Flex Air Pin Box Need to be Deflated at Any Point

Question:

Do you have to let air out to hook up or unhook? Just keep air at 70-100 lbs. all the time. how long will the air bag last or do you have to change every three years or less? I am thinking about getting the flex air pin box #369535 Thank You,

There's no inflation/deflation maintenance schedule for the air bags in the Trailair Flex Air pin boxes like the # LC369535 that you referenced. Whatever PSI rating your towing setup requires can be left in at all times. Air bags are not known for wearing out either. If they were we'd see that question come up as there are so many of these on the road and we sell a lot as well. People requesting replacement bags is basically unheard of. I'd be shocked if you ever ran it to needing a new bag.
