I went out to our warehouse to take the measurement and the Trailair Rota-Flex 5th Wheel Pin Box - Lippert 1621 or 1621HD - 18,000 lbs # LC328330 is 4-1/2 inches from the front base of the king pin to the front of the pin box when you measure for the straight distance. If you follow the curve of the plate it measures 5-3/8 inches. I've attached a photo to assist.

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…
