The hangers aren’t. None of them are. You know why? Because there’s only a 1/2” of space between the stock hanger and the frame rail. I have the MP hangers, I have the Dr. Diff hangers, the offset on the hangers is identical, and it’s a 1/2”.
So the MP shackles are offset 3/4”, and you moved the perches 3/4”. So what? You just side loaded the spring at the front hanger.
Whole thing is moot anyway. 1/2” or 3/4”, the inner wall of the wheel housing is more limiting than the springs once the offset is done, regardless of which way you do it.
