FAQ

What gear is built into the RD-631 top shaft? The shaft features an integrated 48 pitch 20 tooth gear

Is RD-631 required with the RD-630 lightweight spur gear hub? Yes, current Yokomo-derived fitment information specifies RD-631 for use with the RD-630 series lightweight aluminium spur gear hub because the newer hub uses a different fixing arrangement from earlier standard hubs

Does RD-631 fit Yokomo RD SD and MD chassis? Yes, current product listings specifically identify RD-631 for Yokomo RD SD and MD platforms

Does RD-631 include the spur gear hub? No, the top shaft is supplied separately and the compatible RD-630 series spur gear hub must be purchased separately

Important Notes

  • Confirm compatibility with your exact Yokomo chassis and spur gear hub before installation
  • Spur gear hub spur gear bearings and surrounding drivetrain components are not included unless specifically stated
  • Use the appropriate Yokomo top shaft specified for your exact transmission configuration
