Could 18k Rota Flex Pin Box be Replaced with 21k Trail air
Question:
My 2013 Cardinal 3030 which has a gvwr of about 14,400 came with a Trailair Rota Flex 18k. Will the Trailair Air Ride 21k fit my camper. The only measurements that I have made at this point are from bolt to bolt and they are the same on both pin boxes.

Helpful Expert Reply:
If your trailer has a Lippert 1621 pin box style Rota Flex then yes the TrailAir 21k part # LC158778 that you referenced will work well as a replacement. On the pin box you should see Lippert followed by a 4 digit number which will most likely be 1621 since that is a super common pin box.
Also if your pin box has the part number 328330 that indicates too that it's a 1621 pin box.
