Spring rating?

Is there anyway i can Find out what springs and rating I have just by looking at them? Are there any visual differences? I suspect they are upgraded considering that rest of suspension is.

Not TMK without having them tested by a spring shop. How many leafs do they have? 4, 4.5 (half leaf facing forward), 5?
