well i have a 2wd and i thought that i didnt have torsion keys. i just hear a lot of bad things about body lifts so im still not sure about it. i know i can have my fenders shaved a little more but for the same price i could do the body lift like you are talking about silveradotrailblazer. i love my lift so i wouldnt want to screw with it too much. but i dont know. i guess i just have to keep researching the cons of body lifts
