Hi Michael; I'm sure there is a Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box that will fit your 2017 Grand Design Momentum. However, we need to identify your pin box to find the right one. Can you send me a picture of the sticker on your pin box? It will have a serial number on it. If you already know it is a 1621 then the # GY68GR you were looking at will fit as long as your GVWR is 7,275 - 16,360 lbs. You will also need the Gen-Y Capture Plate # GY98FR.
