That would depend on the diameter of the wire in the spring, number of coils, free spring length, and even age and steel composition.
From the pics, I would say that judging by the wire size and less number of coils, that the grey spring has a higher rate, and discounting shock valving and preload, would be stiffer.

I'd say the black one, because it has one more coil.
I might be wrong, I'm no specialist.

More coils = softer springOriginally Posted by dave ytz250s

Oh thanks, I thought that for the same diameter wire if you have a longer wire compressed to the same height it would be stiffer

For a single rate spring, the actual spring rate stays consistent throughout the travel, regardless of how far it is compressed. Same diameter+more coils =softer.
Of course these are not single rate springs, so it will be harder to judge by just counting coils and comparing diameter, and the "stiffness" felt would be a combo of the shock and spring assembly.
I'm stickin with the grey one LOL
