Hey Mark, yes the MORryde X-Factor Crossmember for Standard Frame Hangers # MR33WR is the correct fit for your Grand Design Momentum 21g Thaler as this was designed to fit standard hangers like what your Grand Design has.

installed 3. front/back, middle of axles. on 35' 5th wheel, Keystone. I have a serious 10 point 180 degree turn around on gravel, at the end of each trip, which results in hard scrubbing. Had a engineer buddy come over and suggested making brackets and welding them on the I beams. This looked like it would have the same effect. Been on a year, seems to prevent the leaf spring brackets from bending as I had hoped.

I installed them on a jayco 28bhs. I do notice a difference in overall stability of the trailer, but in fairness I also installed the morryde 300cre hanger kit and switched to a gen y boss hitch. So I can't say for sure which made the most difference. With that said, anything to stiffen the side to side motion of those hangers is worth it. I've torn 2 off on a previous travel trailer. Hunting down a welder to repair them and the downtime is not fun. I also like the fact they are removable as I have a fresh water tank directly above and didn't want a permanent welded beam blocking repair access if needed.

Yes - that is the correct part. We are always happy to suggest that product as it's a huge safety upgrade for not a big price.

I used the MORryde X-Factor Crossmember to beef up the ride inside the trailer (in the past we'd find pictures and accessories all over the floor from driving on our roads). I've also found the towing of the trailer has changed for the positive of not so much swaying. It works for us with our Grand Design 2600RB. I also did a change of adding the CRE3000 to the axles at the same time. The MORryde X-Factor Crossmember was pretty to install if I recall as well. I would recommend the MORryde X-Factor Crossmember. Whatever gives you the advantage of towing for a safer comfortable experience do it!

I added them to the center and back set of shackles on my Brinkley z3100. They removed a lot of the sway when changing direction. I am very happy woith them. They were easy to install too.
