the shocks need to be loop to loop. or eye to eye,
I have an old set of VW bettle front shocks here that fit fine, but the travel down when fitted is only around just under 2" I would need about 4" down travel
the VW shocks that i have here measure.
fully closed 260mm 26cm a bit over 8 1/2 "
fully open, 410mm 41cm a bit over 16"

sorry if this don't make sense.

Going from your first post you need 12" static, and above you need 4" down travel and the VW shock has 16" extension. If you put that together you want a shock with 12" static, and 8" of travel, 8" compressed and 16" extended? Is that right? Do you really need that much travel?

This is what I was wondering also. If the diff itself will move up four inches and down 4 inches, for instance, and the mounting point of the shock is halfway between the pivot point of the arm it is attached to and the diff, then the shock will only see half that movement, or two inches up and two inches down.

I guess the question is, what is the amount of movement you are thinking at the diff itself, how long is the arm from the diff to the pivot point and where is the shock mounting point on that arm, how far back from the pivot point.
