Surprised to see the spring failure and "recurve" at the spring mounting points.
I'm interested in what you did for the replacement springs?

I don’t know the answer to your first question. The tire shop had a Sumo spring display and the technology looked like it made sense so I went for it. I don’t know if it’s a one size fits all scenario or if it’s specific for my particular suspension system.
Both shear springs needed to be replaced. They had extensive cracking, which is very difficult to detect. You have to crawl underneath the axles with a flashlight to inspect.
We considered upgrading the leaf springs but the mechanic said we didn’t need to with the Sumo springs, so we replaced the springs in kind.
