I figure since everyone over here knows about superdutys, I'd ask this question here. I don't own one, or plan to buy one soon. The inspector on my job just got his lifted, and there is a panhard bar on the front end. I asked around on the Donahoe racing website (they make the edge lift kit for them), and they said it was to locate the axle. It is a leaf sprung vehicle. What gives. I just want to know for my own personal info.
