You are correct when you say there is not an air cushioned pin box like the Trailair Flex Air 5th Wheel Pin Box part # LC369535 that goes up to 23,000 lbs. The LC369535 is rated for 21,000 lbs. It sounds like you have a Moryde Pin box which is most likely rubberized which helps to absorb some of the shock while towing already.

Since there is not an air pin box that has the proper capacity for your truck, I recommend to switch out the fifth wheel hitch for one with a better king pin connection. If your truck is a super duty pick up, I recommend the 25K B&W Companion part # BWRVK3305 which has a 360 degree contact with the king pin to eliminate the chucking you are experiencing. Since you already have the air bags on your truck and a rubber pin box, the king pin connection is most likely the issue from our experience.
