01 Super crew 3" Body lift
#2
i would have to ask if you are going to use the stock rims. if so the 35's would probably rub. if you got some rims with more backspacing i think you could pull it off. i recently saw a supercrew with NO lift that had 35's stuffed underneath it. i would not go this route, but if he did it then you could definitely do it with a 3" lift.
