Eric... on a single adjustable shock is the control
valve controlling JUST the extension or does it also
control the compression.... I have a old set of QA-1s
and was told it is only controlling the extension
but they are old.... now I hear a lot of shocks are
controlling both on a single adjustable shock





also on afco shocks that have the single adjustment "window" where you move the adjustment side to side. is this only adjusting extension?

what would be any advantage of replacing the "window" shock with a new double adjustable?

thanks for coming aboard
