Recommended SumoSprings for a 5th Wheel Trailer w/ Axles Below the Springs
Updated 01/04/2023 | Published 01/03/2023 >
Question:
I have a 2017 Grand Design Solitude 321RL. I would like to install your sumosprings but not sure which, if any will fit my rig. I have 2, 7 thousand pound axels with the springs on top of the axels.

Helpful Expert Reply:
Since your axles are below your leaf springs you will want the SumoSprings Trailer Helper Springs w/ Line Relocation Bracket item # SS26MV. These will fit your 7,000 lbs axle. You will need one per axle.
You will want verify that the SumoSprings will fit between your springs and frame. The SumoSprings are 5" tall and 4" in diameter. You will also want to make sure there are no gas lines or other obstructions that may be in the way beneath your camper. These springs do include line relocation brackets.
I have attached a couple of pictures below that will show what this system looks like installed.
