Thinking about replacing my currant king pin with aTrailair Flex Air. I have a 2018 Arctic Fox 27-5L fifth wheel the currant hitch is a MORryde part# RPB72-1716 GVWR 18000 lbs. Will theTrailair Flex Air bolt up and will it raise the front of fifth wheel when connected and towing?

Based on my research, your MOR/ryde RPB72-1716 pin box would have replaced the factory Lippert 1716 pin box on your trailer. The Trailair Flex Air 5th Wheel Pin Box # LC328492 that you referenced is designed to replace the Lippert 1621 pin box, so it will not work on your Arctic Fox trailer.

The closest pin box upgrade we have available to the Trailair Flex Air that will work on your trailer is the Trailair Air Ride # LC158777, which is designed to replace the Lippert 1716 pin box. This pin box features an internal air bag to absorb road shock and will minize chucking and bounce during travel. It has a 21,000 pound weight capacity.

This, along with most other pin box replacements, will not alter the height of your trailer assuming that you use the same mounting holes. It will mount using the same hardware that held your OEM pin box (and current MOR/ryde unit) in place.
