I just picked up a set of dual springs from a forum member. we are both unsure what they are, they came on a set of tfs245's. i am trying to identify them so i can order a set of retainers. any help would be appreciated. here are some measurements i took. sorry i just used a cheap caliper so they may be off a little.

inside spring
.770 id
.900 od
2.430 height (uncompressed)

outside spring
.875 id
1.270 od
2.120 height (uncompressed)

The inside spring has a larger o.d. than the i.d. of the outer spring? That ain't gonna work!

I looked at TFS's site and don't see any springs that match the o.d. you have. It appears that the smallest o.d. dual is a 1.295".

I just did an hours worth of searching and hit all the spring manufacturers I could think of and came up with nothing matching those dimensions. I've seen a few with a 1.275-1.290 o.d., but the inner spring i.d. on those run in the .68X range.

well im an idiot, the id of the inner spring is 0.670. I guess i cant even read the dial on a simple caliper.

and yea. i was confused when the id of the outer spring measured smaller than the od of the inner. But if you think about it, i guess its just the way they fit together. its a tight fit, but these are springs and not two pieces of pipe. there is some give.
