I would be happy to help!

Since the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 3K to 5K - Overslung # TSS-107-40 you were looking at are only rated for 3000-5000lb axles and your Grand Design Momentum 354M has tandem 7000lb axles you will want to go with the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket - Single Axle - 5K to 8K - Overslung # SS26MV.

The # SS26MV are designed for trailers with 5000-8000lb axles that have axles underneath the springs like yours, and do a great job of absorbing road shock but also have other benefits like fighting sway and body roll, and taking weight off the leaf springs leading to longer life for your suspension components.

Since your trailer has tandem axles you will need two of the # SS26MV

I included a video of the # SS26MV for you to take a look at.
