Trailair Flex Air 5th Wheel Pin Box for Lippert 1116 Pin Box

Question:

I want to replace my current stock 5th Wheel Lippert 1116 19,000 LB Pin Box on my Keystone Carbon 337. I would like to do so with the Flex Air 1621, LC369535 21,000 LB vs. the Air Ride 1116, LC155943 21,000. Will the Flex Air 1621 replace my stock Lippert 1116 and fit correctly, or is Air Ride 1116, LC155943 21,000 the only match and replacement? Are there any other Lippert Flex Air pin boxes that would work? The reason I ask is, I read that the Flex Air is better than the Air Ride. Would like to know before I make the purchase from eTrailer. Thanks Erik

The Trailair Flex Air 5th Wheel Pin Box, # LC369535 that you referenced is for a Lippert 1621 pin box and not the Lippert 1116 model. The part number you are looking for is the Trailair Air Ride 5th Wheel Pin Box, # LC155943. This is designed to fit the Lippert 1116 Pin Boxes, and this has a 21,000-pound weight capacity.
