Is it worth it to move the rear hanger for the front springs if you're NOT using longer springs? Will this improve the shackle angle for standard length front springs? I know 7.25" is the popular shackle length, does this add lift or is it equivalent to OE height? I know 52's, etc are the hot ticket but I have some new (regular) 6" front springs that I intend to use. I'm just thinking that this might be an easy/cheap upgrade to do while I have a bare frame to work with.
