Question:

What pin boxes are compatible with a 2022 jayco 321rsts? Currently is just a stock rigid pin box. I was looking at the morryde and curt but not sure what options there are for and easy swap without any modifications Attached picture is what I currently have.

Hey Jimmy, since we know your Jayco Eagle 321RSTS has a Rhino Box pin box installed on it from the factory the best way to improve the ride quality is the Curt Flex Air pin box part # LC65VR. Unlike other options this does a really great job cushioning vertically and horizontally to give you the best ride quality possible.

What other options are there without the flex air ?

@JimmyJ I attached a link to all of the cushioned pin boxes that will fit. We have a MORRYDE part # MR44HR which is correct weight rating and we also have the Gen-Y # GY86GR. I still like the Curt the best though but they all will make an improvement.

@JamesonC will Morryde part number RPB72-FD or Rhino 807712 fot?

@JimmyJ Yep! Both of those part numbers will fit in place of the Rhino pin box you have. We have the MORryde pin box with our part number # MR83QR but the part number 807712 is a Rota Flex pin box we don't carry at this time. For what it's worth the Flex Air has the horizontal cushioning mechanism of the Rota Flex PLUS vertical cushioning so it would be more cushioned but Rota Flex pin boxes are still solid options.
