QTY:1. The latest helical gear Main Drive Gear: suitable for X07/X08/X07W/X15W/X17/X25/X27.
The material has been upgraded to chrome steel, less vibration and noise, the gear is much stronger and we have tested it hundreds of times without any damage.
Helical gears feature greater strength and smoother rotation than the stock gears, improving overall performance of your rc car.
Since the main drive gears have been upgraded to helical gears, we recommend that when replacing the main drive gears, the differential(F28-CS01) need to be replaced along with it.
