What springs should I pair with Rancho 55239 and 55241 shocks?

Springs ???
Any.
Yes seriously. A lot of these mfg have springs made in the same house anyways. Different paint, packaging but same none the less.
...

I have a big spreadsheet of springs with rates and lengths that I have collected over the years. I have yet to find two brands with the same specs.
