Yokomo RD-631 jp 橫崛 Yokomo DP-RS13SP  [RD-631]

This is an aluminum top shaft that can be used for the RD, SD, and MD series. It is compatible with the conventional top shaft (Y2-631), but the D-cut part on the shaft is wider so that lightweight spur gear hubs (RD-630BK/630BL/630P/630R) can also be installed.
