RE: Black foot or stampede?
As for the Diff between the King and Extreme Blackfoot. I know they redesigned the body in the new one (Extreme Blackfoot) and I think they modified the suspension as well. I know the King came with steel bearings in it and a newly re-modified body as well as better shocks, than its predecessor, so there prob isn't much diff between the trucks. But it is a great truck.
