As far as I know I'm running AP 5 inch spring up front I mounted front hanger flush with 5 inch shackle after 2 week of driving my spring started to settle down and shackle starts to hit body mount I call AP they told me that if I have 5 inch spring front hanger need to move 3/4 forward due to longer spring and I did what I was told remount hanger and everything was perfect.
