Progressive rear shock rebuild, where to get spares?

Postby Asp » Sun May 01, 2016 7:07 am



Imported a pair of supposedly good used 1600 series progressive rear shocks for my Aspy recently, but could hear a rattle in one so stripped it down.
As you can see in the pic the larger of the 2 springs has broken.
I've tried emailing progressive suspension but no reply, so does anyone have any ideas where I can get a new spring for these?
I should be able to obtain seals & the rubber eye bushes from local bearing stockists in the UK but the spring is going to be awkward, so guess it'll be another import job.

Seeing as they didn't answer my email I don't think they do want my hard earned £££ :)
Is the spring in the original Honda air shock the same as in the Progressives? There are plenty of cheap original shocks in the UK I could cannibalise.

Thats right you all use pounds. i should have remembered that. I was stationed at RAF Mildenhall for 5 yrs. And my X married for 17 yrs. was from Norwich. :roll:

I dont think the stock springs are the same, maybe,I doubt it, could be. If you measure the spring length,number of coils,diameter of the steel. If they were close or you found some close, change both of them.

I'd try to locate a custom spring maker, I've heard of people doing that for custom Hot Rods. Good luck with Progressive, have the same shocks and after emails and telcons (and bugging them) they advised they have no rebuild ability for those shocks. Mine leak air when on center stand. Let us know how the seal search goes.

Seeing as one of the Progressives was in good order I popped that on the bike, and left the other non-original non-air shock on the other side.

I'd read the GL1500 uses one air shock & one non-air so figured it should be ok.

Pleased to report the ride is quite good, but I'm still hoping to get the other Progressive fixed in the near future.

Custom made spring is a good idea. I'll look into that.

Seal is no problem, its the same as the original Honda one, 36mm x 66mm x 10.5mm, part number 91257MG9671

OK, I guess its time to ask the dumb question. Why use old shocks you cant get parts for that are old technology? Just because its says progressive, dont make it better that newer designs. There is a thing called metal fatigue. Where the metal gets old and brittle and just breaks. So dont be surprised if the other spring breaks some day. Just askin. :shock:

Theres an easy answer to that.
They were supposed to be in good usable condition.
When they turned up it was obvious they weren't, so I set about fixing them.
Its a long way to send them back over your way :D

By the way have you tried to see if there is a 'local' dealer? They may be of more help than the US people. The only way I had a response from them is the telephone, after being on hold about an hour. Per the warranty those springs are a lifetime replacement.

Did you dis-assemble the shock any further?

I only stripped them down as far as the damper cartridge, but hope these pics may be of help with your issue.

I'd guess you could put a spot of threadlock fluid on your damper rod threads & just screw them back in?

There isn't anyone in the UK willing to help sourcing a spring but if you do ever get to talk with Progressive again I'd appreciate it if you could ask them about supplying one, especially as from what you have told me they should have a lifetime warranty.
