Hey I was just trying to get some info about this, I'm sure there is something on this forum about it but I can't really find anything, I was kinda lookin into it and just wanted to know the benifits, disadvantages. I don't really wanna move the axle forward or back is that even possible to keep it were it is. Also I'm trying to equal out about 8 or 9 inches of lift for the rear. I already got a 4 inch shackle flip from ord, what else would I need. Any help would help alot.
