Initial Air Pressure Setting for Trailair Flex Air 5th Wheel Pin Box LC328492


Can you tell me how much air there should be in the donut on my flex air hitch.


Expert Reply:

In an air-cushioned 5th wheel pin box like # LC328492 the amount of air pressure is to a degree up to the preferences of the driver. There is no one set correct pressure for all circumstances. 5th wheel trailer designs vary, and so do their pin weights, so it is usually best to adjust these by feel rather than by a particular spec.

Your initial pressure setting can be based on the yellow sticker on the shock, which has an arrow to indicate a good starting point. Please have a look at the linked video.
