Question:
Will this unit fit the lippert 1621 HD? LC328329

Expert Reply:
There is a Rota-Flex pin box that will replace your 1621HD pin box, but I checked with the manufacturer, and the part number you mentioned will not fit as a replacement. Instead, the correct Rota-Flex for your 1621HD is the following:
- Trailair Rota-Flex 5th Wheel Pin Box # LC328330
The # LC328330 does have an 18,000 lb capacity, so if you were looking for a replacement cushioned pin box with a 21,000 lb capacity like the one in your question, you'd need to go with a different option, the Trailair Air Ride 5th Wheel Pin Box # LC158778.
Either is going to be a big upgrade for a standard pin box, giving you a smoother, more controlled ride, with the difference being the Rota-Flex uses a rubber compound in its head to limit movement while the Air Ride uses an air spring and shock.
