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.
just a correction, the blackfoot has plastic bushings, there is no metal bearings at all. The plastic ones are not even worth thinking about, so buy bearings. The bushings last about 2 runs before the hole is bored out and chipped up by the shafts they ride on. The extreme is just the next generation.im not sure what they did though. I have the ultimate blackfoot though
