when you run rears up front you will move your axle forward about two inches. you will need to get a longer shackle for the rear casue i won't sit flat. shackles are WAY better than a body. body just makes you be able to clear bigger tires. it doesn't help with flex at all. you can add a leaf but thats going to make your flex worse too. just do bigger shackles all around. you'll be a lot happier
