Ive been researching the Progressive 440's for a while now because I don't want to get burned again. On my last bike I put a set of Progressive Air Tails on and the ride was horrible but just about everyone on this site and others said they were far superior than the stock shocks. I had em on for a week , tried every different kind of air setting and couldn't wait to take em off. I just figured that maybe the people who said they were so great didn't want to admit they made a mistake after shelling out $1300 bucks. Now I have an 06 Street Glide and every one is saying that the Progressive 440'ds are the way to go. I was on another site today and a bunch of the guys there said that they thought that they weren't all that great and a few of the guys said they made a clanking sound after rebounding from larges bumps and pot holes and they had a very hard ride. A few said they liked em. Please I'm not degrading anyone in this site and I've gotten LOTS of helpful tips here but it's hard to believe that everyone here says that they are great......Nobody dislikes them? Am I just paranoid after my last(very expensive) experience?
