how come on my brothers setup he's having trouble with the wheels hitting the rear lower fender? He moved his about 13 inches forward with double shackles. The tires doesn't sit centered at all and his tires still hit the rear fender. all i can really think of right now is throwing it far forward than his setup. If it was at 11inch, it will probably do more damage compared the his setup. I just don't know. does the rear not work like the fronts or what? You throw the front axle hanger forward to eliminate hitting the fender when leaf is compressed, but how come it doesn't work in this case for the rear axle setup? wouldn't you want to the rear front hanger forward justike the front axle to avoid this also? Not unless the theory is to throw the axle forward and the rearaxle backward, both reteracting away from the center of the truck. Some body, please help!!!!!!!!!!!!!!!!!!!!!!!!!
