RE: My question on shocks
After reading the responses I received to my question I did a little
browsing.  Based on the responses and the diagrams I found at the websites
of several manufacturers I was basing my question on bad information.  I
find no indication that any shocks today are using a variable diameter
metering rod to control internal fluid flow in a shock absorber.  I was
basing my assumption on a cutaway display model seen many years ago, brand
unknown.  But thanks again for the good and knowledgeable responses.
