You are probably correct. I've read alot of your posts and it is pretty apparent you know what you are talking about, whereas I admit I am a hack...at best (but dang I have a lot of fun!!!). Anyway, I have the pitman arm and drag link. The pitman arm is not dropped but the drag link is. They are off a truck tha thad between 5-6 inches of lift, but the drop in the drag link was not enough to get the steering angle straight enough, so I suspect this will work well for 4" of lift.
