Which SumoSprings Kit for 7k Axle of 2021 Grand Design Solitude 390RK
Question:
We have a 2021 grand design solitude 390RK. Looking to install the sumo spring kit, which kit would work best. I have the 7k lb axles by morryde. Do the springs have a certain capacity to give the ride and stability.

Expert Reply:
The SumoSprings kit part # SS26MV that you referenced is properly rated for your 2021 Grand Design Solitude 390RK and is the correct kit as long as your axles are above your leaf springs. If they area instead under you'd want the part # SS33HR which is same capacity but designed for that configuration.
