For the price you are getting you cant go wrong. If you dont buy it give me the guys address and I will :P

The tranny is fairly tough with the stock engine, you may need to replace the diff gears eventually (like any other bevel gear diff), and as tricksligger said the 2 speed is already on it. You can put pretty much any 2.2 truck wheel/tire combo you want on it as long as it uses a 12mm hex mount.
