Q: Who actually makes these springs?

They are produced in an engineering partnership with HYPERCO, a spring supplier to Formula 1 and a maker with more than 50 consecutive Indy car wins behind it. The whole set is designed, engineered, and produced in America. That motorsport pedigree is why the dual-rate behavior stays predictable and repeatable instead of feeling vague at the transition.
