I believe you are simply asking the length of the king pin on the Trailair Rota-Flex 5th Wheel Pin Box # LC328330. I reached out to the manufacturer who said that the king pin on this pin box measured 3.29 inches.
I have added a photo showing other dimensions of this pin box for you to take a look at as well; this pin box is a direct replacement for Lippert 1621 and 1621HD pin boxes and is designed to make your towing experience more comfortable with the rubber compound in the pin box head that acts as a shock absorber.
I've also added a link to a video review of the Trailair Rota-Flex 5th Wheel Pin Box # LC328330 for you to check out.
