Details on my shocks?

I am trying to do some shock math and I need to know the compressed/body/extended lengths on my current shocks but not having much luck finding it.

They are a Rough Country 4.5"-6" Lift.

I believe they are made by Heckathorn and the part number is 651896.

I have been searching google and rough country's website doesn't say anything about them really. If anyone can pull info, its much appreciated.
