Question:

I currently have a lippert pin box LIPP1621 15500lbs. Do you need any more information from me to discuss our pin box upgrade options? I was looking into the Lippert products and Mor Ryde. Thank you,

The information you provided is perfect! The weight rating and the "1621" number you found is exactly what I'd need to know to confirm replacement pin box options.

The Lippert options we have include the Rota-Flex # LC328330 and the Trailair Flex # LC328492. The Rota-Flex is basically a step up from the basic 1621/1621HD pin box # LC1191191 in that the head can pivot some to help with ride quality. The Trailair uses a rubber compound in the head assembly as well as an air bag and shock to give you much better performance while towing. This would be the premium Lippert option.

At this time we don't carry the MORryde pin boxes but if I'm being honest I've heard good things about the way they perform and people tend to like them overall.

I do have one other option that I think you'll really like and that is the Reese 5th Airborne Premium # RP78FR. This pin box is arguably the best option on the market and most people actually upgrade their Trailair to this pin box. Don't get me wrong, the Trailair has it's place and purpose, it's just I've seen that this tends to be what RVers gravitate towards and we get really good feedback on the 5th Airborne pin boxes.
