From what I was told the outers don't get flipped, they just stay the same and once the bumper is raised they are right, in the kits they only have a bracket that bolts to the frame in the stock holes to raise it up and let you bolt the outer brackets to them.
The ones you flip switch sides and rotate 180 are the inners. I couldnt understand the flip and rotate 180, do you flip them long ways front to rear then rotate from side to side meaning inners to outer, or vice versa or what? Maybe only one bolt goes back in them and not 2? I tried to look at it when I had it apart but thought eh, I'll figure it out if I ever get my body lift.
