They are linear, which was another reason I went with them (especially with the Swift spring upgrade, which provides a more consistent spring rate as more and more load is put on the spring). Seen testing between springs that came with a set of coils (not BC but another brand) vs swift, and things were relatively consistent until you really put a lot of force on the spring. That's where the swift spring kept its consistent rate and the other spring did not.
