Stock coils measure 12" front and 8" rear. Measure yours and compare. The difference is the amount of spring lift. You may also have a body lift and/or a coil spacer lift. Pics of your springs and body mounts will help.
To find out amount of suspension lift, measure your front springs. Stock springs are about 12" at ride height...anything over that is amount of lift. Also see if there are spacers on top of the springs. If so measure the height of them...that would be the amount of budget boost lift. You could also have a body lift. Measure the distance between the frame rail and the tub inside a rear tire where the frame goes up over the axle. Stock height over the frame there is about 1/4", so anything more than that is the amount of body lift.
