Lightnings are 1" lower than Standard F150s, right? How is this accomplished in the rear? Is the shackle 1" longer than stock? Don't mean to be an endless nag here on the board, but if I want to raise the rear of my truck 1" I am wondering if changing out the shackles, down from the 2" ones is an option. I don't think the ones I have installed now are adjustable.
