FAQ
Does RD-630BK fit Yokomo RD SD and MD chassis? Yes, Yokomo officially lists RD-630BK as a lightweight aluminium spur gear hub for the RD SD and MD series
Do I need a different top shaft when upgrading from an older Yokomo spur gear hub? Yes, when replacing standard hubs such as Y4-630A Y2-630PA or Y2-630RA, Yokomo states that the set-screw location is different and the dedicated RD-631 top shaft must be used on compatible RD and SD setups
Can RD-630BK be used on MD-series cars? Yes, but MD3.0 applications require the appropriate MD-series top shaft such as MD-631 or MD-631-35 depending on the transmission setup
Does this upgrade change the gear ratio? No, the hub itself changes the spur gear support and position rather than the spur or pinion tooth count
Important Notes
- When replacing Y4-630A Y2-630PA or Y2-630RA on compatible RD or SD chassis use Yokomo RD-631 top shaft
- MD-series installations require the appropriate compatible MD top shaft
- Yokomo states that this hub cannot be used with the Y2-018AR2A aluminium rear shock tower
- Compatible RD and SD installations require the RD-018AB rear shock tower where specified by Yokomo
- Spur gear top shaft and surrounding drivetrain components are not included unless specifically stated
