ahhh I get it now!
I will have to measure mine, I was thinking I set at 6" front of the running boards and 7" rear of the boards. I found that going lower than that LOOKED AMAZING but with the rake, the bottom of the front bumper would scrape the crown of some of the older asphalt roads around here haha.
here is a vid of my 47 gmc, set at 4.5" front 5.5" rear, click the pic to play
