Just like any other spring, you change the angle or induce more tension, it has less room to travel.

That's interesting if the stock bolt only has one cotter hole? The FSM has a section on ride height, I wonder how they say to adjust it if you can't move the castle nut through a very wide range?

You have roughly maybe 5mm of adjustment with the castlel nut and cotter pin.
