Hi JohnK

Congratulations on the Reflection and welcome to our owners technical forum. When you have a chance, have a look at our welcome post. https://gdrvowners.com/forum/main-fo...to-new-members . This will help you set up your signature and navigate the forum.

It is possible that another owner on this forum will know the answer to your question . . . but this sounds like something that you should ask Reese directly. They will want to know which pin box the trailer was built with originally. Probably an LCI 1621 but . . . that's just a guess on my part. Look for a label on the pin box. If there is no label, contact Grand Design Customer Service (contact info on the right side of our home page) with your VIN and they will be able to to confirm the OE pin box.

Like above, you most likely have a LCI 1621 pin box, but you need to verify it. If you do, the part number is #68220 for the regular one, and #61422 for the airborne version, which has the air ride. I have the regular Sidewinder (20K) on my trailer as the airborne one does not have the weight capability for my trailer weight.

You will also need to buy the correct wedge for the hitch that you have. It comes with a generic one, it works, but depending on what you have, is very sloppy.

JohnK Welcome to the family and the forum!

You guys are correct and what a great guess, it is a 1621

And thank you!
