Here are some pics on how the shock is mounted outside of the frame rail. I'm using Global West UPC's and stock lowers. Wheels are 17x9.5 with 5.5" back space. It rubs frame rail loc-to-loc but not enough to be an issue. Front fender lips will also have to be rolled. Depending on how low you go with the front you may have to take a baseball bat and roll a bit more.
