yah i guess i didnt read all the install instuction and i sold the hanger a couple of weeks ago. im think about duals and a hp diff. that looks like it should work.
If you don't mind me asking why did you choose to go with All Pro's biggest lift? What size tires are you planning on running? I know that they recommend running their front hanger with anything over their 4" lift kit (using 1.5" over stock shackles). Anything under you can scrape by without having to install it. If for some reason you can't do the dual cases i would say just drastically reduce the amount of lift.
everyone keeps asking what size tire i plan on running is about 35s to 37s. i listen to a friend who bought the same lift and i like the way it looked. i know it over kill for those tire but the next build up ill do no more that a 4" lift. i guess you live and you learn from your mistakes.
