Replacement 39-tooth spur gear (32-pitch). Traxxas spur gears let you fine-tune the performance of your Traxxas model. Changing gear ratios can help balance torque and speed for different surfaces. Please consult your owner’s manual for more information on recommended gearing options for your specific model.
This comes standard on Traxxas TRX-4 Sport and Sport High Trail but can be fitted to any TRX-4 or TRX-6 variant except TRX-4M.
