[A useful part for improving RC car performance and maintenance] This O-ring is made of a material with a good balance of expansion and lubrication to maintain gear differential performance over the long term. The size takes into consideration the airtightness and low friction required for gear differentials. Its resistance to expansion reduces the frequency of maintenance. Its hardness is set at 40��. ensuring stable gear differential operation. It is primarily designed for electric touring cars.
