For new leaf springs for your 2019 Grand Design Solitude 5th Wheel you'll need to know the axle capacity and measure the leaf springs to find the correct replacement. I've attached some diagrams below for both double-eye and slipper spring style leaf springs. I'll need measurement A for both spring types.

For example, If you had a 5k axle capacity and a 30" eyelet to eyelet measurement on a double-eye leaf spring then you could use part # UG34FR. If you can get me some more info on what you currently have I'd be happy to find the correct replacements.

I see you were looking at SumoSprings for trailers as well. If you're trying to find the correct one then you'll just need to know the axle capacity and whether or not your axles are overslung or underslung. If the leaf springs are above the axle then it's overslung, under the axles would be underslung.

The SumoSprings Trailer Helper Springs w/ Line Relocation Bracket # TSS-107-40 are designed to work 3K to 5K rated axles that are overslung. If you need help find the correct ones I'll just need more info on your axle and leaf spring setup.
