This is an optional Traxxas Mini Maxx Steel Spur Gear (47T).
The 47-tooth spur gear (32-pitch) is made from steel for maximum power handling and durability and fits directly onto the center driveshaft. Traxxas spur gears let you fine-tune the performance of your Traxxas model. Changing gear ratios can help balance acceleration and top speed for different running conditions. Please consult your owner’s manual for more information on recommended gearing options for your specific model.
