Determine right size shocks for unknown lift?

[Seven3_AH]

Anyone know how I should go about determining what size shocks I should get for my SAS swap? I have no idea how big my coils are supposed to be. As of right now I can barely fit my 38.5s (I'm going to cut my fenders as its a mud) but I'm having trouble figureING out what size shocks I need.

Got a forklift? (or access to one?)

Pick one of your rear tires up enough just until another wheel lifts off the ground (contorting the suspension). Then measure the extended distance between your shock mounts and see if you can match that up in a shock catalog (also make sure the minimum distance on the other side isn't less than the shock's compressed length).

You can do the same for your rear shocks, except in this case you'll want to lift up a front wheel.

In case you're wondering, lifting up from the opposite end forces the end you're checking to flex more (due to weight transfer).
