Question:

I have a 21 Grand Design Momentum 395M and I am interested in sumo or sumo type springs for the 3 axles. Can you point me in the direction to help from it bouncing all over

Helpful Expert Reply:

I recommend using the SumoSprings Trailer Helper Springs # SS26MV on your 2021 Grand Design Momentum 395M. These springs are rated for use on axles with a capacity of 5,000-8,000lbs and are mounted below the leaf springs. Your Momentum has three 7,000lbs axles that are mounted below the leaf springs.

It is a good idea to verify that the springs will fit between your springs and frame properly. The SumoSprings are 5" tall and 4" in diameter. You will want to verify that they will fit and not contact any gas lines or other structures that may be under your camper. The springs will include line relocation brackets if the gas line is in the way. When installed and the trailer is sitting level the springs should just begin to compress on the frame so that they will best absorb road shock. Included with the springs is also a 1/2" spacer that will help adjust the height for the correct fit if your springs sit a little higher.
