I checked the Grand Design website for details on the pin box installed on your Momentum M349 but they do not include that detail in their specs. Usually you'll find the pin box part number on the box's driver's side sticker. This is needed to select an appropriate replacement cushioned pin box that will bolt right up in place of the OEM model.

You can use the linked page to select that OEM part to then see the compatible cushioned pin boxes, and cushioned pin boxes that also include a Sidewinder turret; this type provides 22-inches of additional turning clearance (needed for beds shorter than 6-1/2-feet).

A popular pin box on heavier trailers like your M349 (16.5K GVWR) is a 1621HD so we'll use that for an example. If you click on the link provided you'll see our main page for all cushioned pin boxes. Click on 1621HD to see the bolt-on replacement cushioned pin boxes that will fit directly in place of it. For this application we offer 5th Airborne pin box # 5AB-E1621-610 and Sidewinder version # RP61422.

We do not offer Pull-Rite capture plates but according to their website the correct ones for a 5th Airborne pin box are 331759 and 331760.
