Mine is just a little under 25" in the front measured to the bottom of the molding at the wheel opening and about 25.5" in the back. (I let the air out of my Air Lifts in the back to make sure that they didn't effect the readings. I realize that body-to-frame differences as in rotten bushing or different bushings could make a slight difference when measuring this way. My body-to-frame bushings are still stock with 116k miles.)
Are my measurements typical for these springs? I am scraping much more than I would like to and the 3 front deflectors have a very short life expectancy. I added new ones not too long ago and there are no survivors. I will probably put a set through a table saw to increase clearance.
