Progressive Shock Identification

[Dr Bobs Patient]

I just got my own Phat Gurl several weekends ago.  Put on a new rear CT tire and found the rear shocks have a Progressive sticker on them.  Is there anyway to identify what model they are?

I put a CT 205/55/26 on and it rubs the nut cage when we're two up.  I won't mind doing the nut cage mod, but is there anyway to adjust those Progessive shocks to raise the back end up a little?

Thank you in advance for any help.

I don't know how to identify one Prog from another without a photograph. If you want to firm up the ride, adjust the top nut to put more preload on the shock. Turn it clockwise when looking down from the top. If you can raise the bike and measure the length from hole to hole, you'll know if you have a stock length or a shorter version. 13" is stock length.

Like Sandy said, measure from eye to eye, for length.  As to if they are 412's or 440's, the 412's are like the stock shocks in that they have 5 adjustment positions, from firm to soft, and use a similar adjusting wrench as stock...  The 440's have more or less an infinate adjustment from firmest to softest, with the adjustment being done like Sandy said.  I have the 412's, so I'm sure about those.  For 440's, maybe someone knowing more will chime in.

PS 440s come new set to the softest setting, and can take ten full 360* turns of the top cover to add preload.  As 440s are turned, threads appear at the top, supposedly one thread per revolution of preload.

That said, I doubt stiffening up your shocks will stop your tire from rubbing the nutcages.  Adding preload may make travel more difficult, but does not increase height or stop travel.

I'll get a picture posted later tonight.  At work right now, but it does look like the one above, 440.

There wasn't a tool or tool kit with the bike, so I'll have to MacGyver a tool to turn the preload cap.

After they've been on a while, they are a bitch to turn by hand, esp if you have the hardbags (4 bolts remove them).  Jacking the bike up just enough to take the weight off them (tires still touching), also helps.  A small strap wrench will work, there is no tool for 440s.

Thanks for the heads up.

+1 what Jess said

Ive often wondered what if the both sides were not turned to the same # of threads on
my 440 HD 13's

Next time I have the rear wheel off for a tire change I will check how many threads
widths mine are set at

How are yours set

Here's a picture of the shock.  It appears to be preloaded now.

Looks like the 440's. At least the ones I use to have.

OK, now that I have learned all I ever wanted to know about Progressive shocks, it's time to just do the nut cage mod!  Gives me something to do this weekend, as if I didn't have enough to do already!
