Help with rear shocks ID

I bought my 78 GS with these Progressive Suspension shocks on the back. At first I thought they were siezed because I couldnt get them to compress at all. I took the springs off and cleaned the shafts and found they were rust free and moved freely but needed quite a bit of pressure to make them move. The numbers on the shock body do no correspond with any Progressive Suspension has in a current catalogue. As a matter of fact the shock body has the S&W insignia stamped in the side which reminds me of my S&W strokers from back in the day. The upper plastic covers (i took them off for looks) had the PS decals on them. I am looking to soften up the rear by either swapping the 2 piece springs for a single progressive or buying some other shocks altogether. I would like to find out about these so I can at least try and sell them. Does anyone have any leads as to where I can find some info? My guess is that they are PS shocks from the early eighties.

I cant reload the pic so here is the original link

They look like S&W spring setup not progressives... Progressive don't use 2 springs like that.

I would suspect they are S&W but perhaps with a set of the plastic bits from a progressive shock. Strange! :)
 
That sure helps! I will continue my search with the phrase S&W rather than Progressive? Brilliant!
 
Where is this picture of the rear shocks?
I looked through the linked thread and did not find it. :confused:
eye-to-eye or eye-to clevis? Center-to-center of the mounts?

Its midway down on page 2 of the thread (small pic). Turns out Progressive bought out S&W maybe these were hybrids. It looks like Progressive springs will fit, now to determine the rate.........
 
Do they look like these? (Without the D.O.T. tape around the top cap)

Make me an offer I cant refuse. but before you do let me take some more pics so you can be sure you want them. The shafts are perfect and the dampening works perfectly through the stroke. The powder coat on the springs is pretty good but its falling off the top collar and preload adjuster.
 
What parts were you looking for again?
850 piston, valve shims, head light or headlight ears and what else?

Eric
 
:lol: I got the pistons this week and I am good on parts right now, but let me think on it for a bit. I could use a front master cylinder from a newer model twin caliper Suzuki for my SV650 caliper set up.
