Question:
I have a Lippert 1621 HD pin box with an 18K rating on my 5th wheel. I want to replace it with a rota-flex pin box. My hitch is a Reese Pro 20K. Can you tell me which rota-flex pin box to get, and do I need an additional plate?

Helpful Expert Reply:
The correct Rota-Flex pin box you need to replace the Lippert 1621HD you have on your trailer that has an 18k weight rating is the part # LC328330. This provides front to back cushioning with the cushioned pin box plate.
If instead you wanted vertical cushioning in addition to that we have the Flex Air part # LC328492 which I recommend highly. This is the most effective cushioned pin box solution available for your trailer.
Question:
I still have a question about needing any additional items for hooking up Do I need a capture plate??

No capture plate would be needed nor would any other similar adapter be needed. Your current Reese hitch would connect directly and work really well!
