I think he is looking to see if he has any type of lift. Anyone have a stock height to the rocker pannel? Mine is 23" with 33" tires and 3 inch BDS from the ground to the bottom of the tub right infront of the side step.
I was told to measure the gap between upper and lower spring perches in the front, 11" is stock, anything beyond that is the amount of spring lift you have. Way to many variables for a ground up measurement.
