It sounds like you are talking about the air bag that is in the front of the Flex Air pin boxes, such as # LC328492, or the rectangular rubber piece inside. If you need to replace the air bag I would need to know which model Flex Air that you have. If the bag is not holding air then it is likely the Schrader valve and not the bag itself.

If you are talking about the rectangular rubber compound on the inside it too could be replaced. When Lippert was here recently to provide product training they did indicate that basically every piece can be replaced.

The pin box does not require a lot of maintenance. Basically keep the pivot points lubricated and make sure the air bag is not leaking.

What was meant by neutral forward to back is that there is a middle setting that puts the jaws of the hitch in the center most position available. That would be what I would start with. The height range of the #BWRVK3600 is 17 to 19 inches measured…

Because it's lighter, less expensive, has fewer moving parts and is mechanically less complicated I'd recommend going with the Gen-Y #325-GH-8040 shock absorbing pin box versus a Trailair Flex Air like part #LC328492. The Trailair features a…
