I reached out to my contact at Lippert who said that the current Rota-Flex you have on your 5th wheel trailer is the part # LC176440 which is rated for 19K and pin box number 1116.

The correct Sidewinder replacement is part # RP61412 on our site which is rated for 16K. This comes with a universal wedge to lock out the king pin but if you can tell me what 5th wheel hitch you have I can let you know if there are any custom wedges that would offer a better fit.

Please also note the attached photo that lists any 5th wheel hitch compatibility issues.
