This is an optional Double Bearing Front Axle Set (Drift) for the Yokomo RD/SD/MD series.
The double bearing holding the axle shaft distributes friction and reduces rotational resistance of the front tire to the utmost limit. Axle shaft is made of steel but only Φ3mm to reduce weight and rotational moment. The front-end rolls better during acceleration, increasing acceleration at the exit of corners and preventing spinning. Tread adjustment is also possible by replacing the spacers.
