If your upper and lower shock mounts are already in place, then the extended measurement is of little use. Just get the compressed length required by ramping the rig, subtract a little (3/4" to 1") and establish this as the compressed length for the shock. Then refer to the shock catalog and select the longest shock that matches your compresses length number.
The extended length is a consequence......
OK, some will say that this could lead to the shocks max traveling on full extension. However, this is a relatively rare situation, only found on rigs with massive travel. Also, on a leaf sprung rig, the hanging weight of the axle is at least partially suspended by the springs, so the shocks won´t see the full pull of the axle weight.
On my coily Samurai, my shocks do in fact max travel on full twist. But full twist is a rare enough occurance for my wheeling that I have had no problems. Also, my suspension starts to bind at around this point, so the down travel velocity is dampened before the Ranchos come to their extended limit.
But I am looking into limiting straps, just the same.....
