RE: Progressive Mono Tubes
Here is a pic of both PMT's. The one on the top is my original and the bottom is the replacement I bought before I received my replacements under warranty from Progressive.
The replacement I bought is different, the spring is thinner and you can see the closeness of the spacing between the winding is different. The progressive windings are almost non existent.
I did use one spacer on my old set but on the replacements I went with the recommendations in the instructions and by a parts counter person where I bought the replacements at. (They exclusively work on ALL YEARS GW's), so I trusted what he recommended. It was late in the night and I had to get my transportation done, so I can go to work. When I pushed the GW off of its center stand, I noticed that the front dropped considerably, almost like when my OEM springs were in there.
One shim does make the ride a little stiffer but I think with the shim, big bumps with the big jolts to the rider are better handled. The front of the bike was at OEM ride height, maybe a few millimeters higher because the GW leaned a little further than it did with OEM springs.
