Bruce, curious if they are stamped with a code or actual capacity to determine what the weight capacity is. I have several sets of springs and would like to know what their capacities are

I don't think these are stamped. Measure the diameter of the "wire". Sean and I figured out the rate of the spring based of the diameter material used to make them. I think it was that every .5 mm in diameter over stick increased the rate 20 lb over stock 100.
