If the shock has a bit of slack between up and down motion, then you can get
vibration.  It's not enough that the shock can still dampen movement, what
you don't want is something like a 1/8" or 1/4" of free play up or down
before the dampening kicks in.  If that happens you can get a little bit of
the harmonic vibration...
