Has anyone had problems with Progressive Suspension 440 IAS Series ?
I just installed them for a friend last week, but they are too soft. No damping at all

I have the same suspensions on my Valk, and they are totally different... the works! Perfect !
Dag, you didn't say if these were 4412 (HD) or 4213 (std rate) springs (aside from the springs, the two shocks are identical).
I was informed by a progressive tech that it takes 8 of 10 possible turns on the std shock to equal the dampening of the HD at the lowest setting. I have HD on my IS (which progressive does not call HD...they call them std for IS, which causes a lot of confusion), and they are perfect for me on the lowest dampening setting (solo at 185lbs, with or without a medium load). But I recently put std rate 440s on my supervalked IS, and the lowest setting (which 440s always come set at when new) was too soft. I turned them up three turns each for the upcoming Blue-Grey ride, and a test ride seems good.
Turning the top shock cover clockwise increases dampening, counterclockwise decreases it. There are tiny grooves which appear at the top of the shock as it is turned clockwise to increase dampening, but I felt better counting full turns from the bottom.
I'm think this is on the progressive website, but not sure.
They carry a lifetime warranty, if you have a receipt, but shipping to/from Norway will be a PITA.
