GDT Spring help!!

[kiwi]

the top hat collar sounds like the adapter for a ods mcu to spring conversion.I though the gdt were pretty much identical to the noleens.All complete guess work as i have never seen a gdt.[smiley=worry.gif]

I went in search of springs today at some of the local shops.  No luck.  They either could not (or more likely would not) give dimensions on springs they could order.  They seemed to have little interest in assisting with a ten year old bike.  Anyone got dimensions on some springs?  Looking for probably a 350lbs or so spring rate.  Anyone using any Manitou springs that would fit the bill?  I think the Rapid Descent springs may work.  Anyone got exact dimensions on them; inside, outside and end-to-end?

i jut looked at the pics.There are two issues.One is there has to be the angled fitting that bolts up to the strut,but this can probably be transferred straight over from the old  shock.As someone has already pointed out there is no bottom collar.are you supposed to use the bottom washer of the elatomer stack?That would not center or locate the spring.Has any one got a gdt setup?What locates the spring at the strut end?.Once we have taht sorted we can determine the spring length!

I remember that my GDT had a spring locater that was made from plastic. Maybe .06 to .08 inches thick with a lip that caught the spring. The reason I remember is that it was cracked and I used it anyway. I believe the adjuster was plastic also.

And it had a yellow spring. 300 to 350lb rated. Maybe Iron Horse part sales or Noleen shock service can help.

I still think a noleen spring will fit.

If all else fails, send your shock to Risse Racing for thier spring. They have sure helped me out. If they can't, at least they can tell you why.
