Okay, so are they binding the lighter coils during travel? I don't see any crossover ring, so that is the only way this produces a dual rate. Otherwise, as we all learned in physics, 1/keq = 1/k1 + 1/k2. Putting two different rates on a single coil does not magically make a dual rate spring, no matter how much marketing claims it does. I'm sure this is a nice spring, it looks like a nice spring, and it sounds like they went through a lot of trouble to make sure it was manufactured as a nice spring. I just don't...
