Product Description Type: Radio Control Manufacturer: Tamiya Type: RC Parts Radio Control: RC Limited Parts Radio Control: Pop-Up Options Compatible Cars: DB01 This is a used DB01 gear differential unit, a rare and valuable option that is no longer in production, for sale. ♠︎ The combination of a one-way in the front and a gear differential in the rear changes the handling compared to front and rear gear differentials. When cornering, releasing the throttle allows the front to become free, enabling smoother turns. Also, the front locks up on acceleration, making it easier to accelerate, which is quite fun! ♣︎ Cleaned. There is almost no wear on the bevel gears inside, so I think it can still be used for a long time! Thank you very much.
