Daniel,
There are 2 springs in the valve assembly. The small one controls the
rate
of the arm going down (spring in extension), the larger controls the arm
going up (spring in compression). Each of these springs can be modified
separately without affecting the other, contrary to merely changing
viscosities. The large spring is either changed to a heavier rate (TR6,
AH3000) or shimmed where it sits on the valve (i.e. not shimmed on the body
or inner end), or both. When you take these valves out you'll usually find
shims. If not, grab some off of some other shock. The small spring is
adjusted by tightening the tiny retaining nut you'll see. These are silver
soldered but are pretty easily turned. You can try to re-solder, or not.
Pictures with circles and arrows (and a paragraph on the back of each one
showing... never mind) will be posted on our page this month. At least that
is my goal.
And a Happy New Year to you.
