Is 21,000 lb Trailair Flex Air Pin Box Compatible With Curt Q20 Sliding 5th Wheel Hitch

Question:

Hello I’m interested in purchasing the FLEXAIR 21k and I want to confirm that it will adapt without any issues to what I currently own. Therefore I have a Q20 with the 12inch slider then mounted to a base for the 2020 GMC 2500 6’10” 2500 pulling a 2011 Dutchman 31’

Definitely a good idea to make sure a purchase like this will work without issue, and I can tell you that your sliding Curt Q20 5th wheel hitch is 100 percent compatible with the 21,000 lb Trailair Flex Air 5th Wheel Pin Box # LC369535.

The only pin box the Q20 is not compatible with is a rotating pin box like a Sidewinder, but the Flex Air isn't rotating, it is just a cushioned pin box, so it will work wonderfully with your Q20 and you'll get a much smoother, much more comfortable ride as a result.

The 21,000 lb Trailair Flex Air 5th Wheel Pin Box # LC369535 is a replacement for a Lippert 1621 pin box, which I'm sure you knew but I did want to at least mention in the interest of being thorough.
