Expert Answers about 5th Wheel Pin Box


  • Is There a Trailair Flex Air 5th Wheel Pin Box To Replace a Lippert Model 1116 Pin Box
  • In order to replace your Trailair Pin Box Model 1116, I recommend the Trailair Air Ride 5th Wheel Pin Box Model 1116 part # LC155943. The Trailair Flex Air 5th Wheel Pin Box Model 1621 part # LC369535 will not work. The Trailair Air Ride 5th Wheel Pin Box is the same as the Trailair Flex Air 5th Wheel Pin Box save for the pivoting head but there is not a Trailair Flex Air 5th Wheel Pin Box offered for a Model 1116.

  • Compatibility of 5th Airborne Air Ride Pin Box with Curt Q5 Cushioned 5th Wheel Hitch
  • The # 5AB-E1621-610 5th Airborne Air Ride Pin Box you mentioned can be used with the Curt Q5 5th wheel hitch. It is the 5th Airborne Sidewinder that is not compatible with a cushioned 5th wheel hitch like the Q5. The Air Ride Pin Box you need will depend on which OEM pin box you have on your 5th wheel. The manufacturer and model number of your pin box should be printed on a sticker or plate stuck to the pin box. The # 5AB-E1621-610 you mentioned is compatible with the Fabex 665, Lippert...

  • Can The Trailair Flex Air Pin Box Be Used With The Andersen Gooseneck and 5th Wheel Adapter
  • Lippert states that the Trailair Flex Air 5th Wheel Pin Box # LC328484 cannot be used with any type gooseneck/5th wheel adapter. This would include the Andersen Gooseneck to 5th Wheel Adapter # AM3200. The manufacturer has determined that the Trailair Flex Air pin box must use a traditional 5th wheel hitch.The issue with this particular pin box is there is not enough stability between the movement of the pin box and the movement around the gooseneck ball.

  • Yes, the Trailair Flex Air 5th Wheel Pin Box part # LC369535 will work perfectly with an Anderson Ultimate 5th Wheel Hitch. I have spoken with Anderson in the past and they have given the go ahead for using their 5th wheel hitch with a cushioned pin so you will be just fine. The note on the product page for the Trailair Flex Air 5th Wheel Pin Box states to not use this with a gooseneck to 5th wheel adapter but this is more or less referring to those that bolt to the bottom of the pin...

  • With The Andersen Ultimate 5th Wheel Hitch And Airborne Pin Box Allow For 90 Degree Turns
  • The 5th Airborne pin box being referenced in this question is not a Sidewinder/rotating pin box. It's actually just a standard air cushioned pin box like the # RP78FR. The degree of turnability with this setup will depend on the following factors: 1. The distance from the center of fifth wheel hitch jaw to the truck cab. 2. The length of king pin to the nose of the fifth wheel. 3. The width of trailer divided by 2 (to get half). For example: If the distance from the center of the...

  • How to Determine Correct 5th Wheel to Gooseneck Pin Box to Tow 5th Wheel Trailer w/ Gooseneck Hitch
  • Hi Jaime, So it sounds like you are wanting to replace the pin box on your 5th wheel trailer with an adapter that connects to a gooseneck ball. That is definitely something you can do, but there isn't enough information here for me to answer what would work best for you. Reason for that is the specific pin box model and your trailer weight is needed to get the right adapter. For example, if your 5th wheel trailer has a Lippert 1621 pin box, weighs no more than 21,000 lbs, and has a 2,500...

If there is no sticker or plate on the pin box indicating the manufacturer and model number of the pin box then there are some measurements you can take to determine which pin box you have. I have included a link to a help article that explains the measurements needed.

  • SuperGlide and Demco Highjacker Auto-Sliding 5TH Wheel Hitches Locking Plates For Basic Pin Boxes

Locking plates are only required for cushioned and other specialty pin boxes that do not fall into the 12"-14" pin box width.
