The only difference between the Curt Flex Air and Lippert Trailair # LC155943 is simply just the name. Lippert purchased Curt awhile back and has been rebranding some of their products under the Curt name so as we go through stock the Lippert Trailair name will eventually go away. The real difference maker here is going to be the bolt pattern of the pin box on your trailer. The # LC155943 is designed to fit an 1116 bolt pattern.

If you look at your current pin box there should be a tag/sticker somewhere that has an RPO number and Serial Number that we can use to determine the bolt pattern. If not then you can use the attached help article below to take some measurements and determine the bolt pattern and then we can find the correct replacement Flex Air/Trailair pin box.
