Traxxas Wheelie Bar Assembled -T-Maxx 3.3 Fits All Maxx This assembled Traxxas Wheelie Bar has become almost mandatory equipment for the new more-powerful Maxx cars. Able to fit all Maxx cars, the wheelie bar has 4 snap-in adjustment positions that allow you to choose how extreme you want your action to be. In the down position, it keeps the front end of your Maxx truck planted to show off the incredible acceleration possible with the TRX 3.3. Raise the wheelie bar to its full-up position and the action gets wild, with giant wheelies that hang on as long as you keep mashing the throttle even through second gear! The unique design allows it to be easily removed in situations where you may not want the additional control.
