How to measure shock stroke?

[Revol]

I've installed a BETD long travel link on my Y2K FSR Rockhopper and I need a stiffer spring to use the 5" travel setting.
What I need to know is:When measuring the stroke of the shock is it measured from the body to the spring collar or from the body to the bottom out bumper?
The shock is a Fox Vanilla (OEM model,no rebound etc) measuring 6.5" eye to eye.There's no writing on the current spring BTW.

Cheers.

I would say it is the distance from the shock body to the collar. Otherwise, the spring would bottom out before the shock. Not a good thing:(

Most 6.5" eye to eye shocks are 1.5" stroke. As long as the spring will physically fit on the shock and has at least that, it should work for you.

measure it along the shaft from the bottom of the body to the bottom of the bottom out bumber.

Thanks fella's.
1.5" stroke sounds right.Just wanted to make sure before I worked out the leverage ratio etc to decide what weight spring I need.

shock stroke : eye to eye length ratios are usually pretty standard. So I would agree with what has been said so far, 1.5 inch stroke.
