[Nor Cal Al]

The three positions were stamped into the upper half of the shock and I believe there was an index on the lower half. I do not know how the adjustment was made. I never changed mine from normal because the ride was already too stiff. I believe there is something about rotating the upper part while holding the lower part, I don't know if it's one full turn or just move to the next index mark. A Gabrial dealer should be able to help you.

I would like to find some air springs for mine. It is a very rough ride on bumpy roads.
