This lightweight spur gear hub is compatible with Yokomo's RD/SD/MD series drift cars. While boasting a stylish design, its larger diameter enhances the spur gear's hold, resulting in smoother, less wobble rotation.
Furthermore, because the spur gear is positioned closer to the gear case than before, it reduces stress on the top shaft during rapid acceleration, providing a more direct and responsive feel.
*When using this product as a replacement for the standard spur gear hub in the series (Y4-630A, Y2-630PA, Y2-630RA, etc.), please use it in conjunction with the dedicated aluminum top shaft (RD-631)
