Spur gear hub for drift chassis

The RD-630P is a lightweight spur gear hub designed as a direct replacement part for Yokomo drift platforms in the RD, SD, and MD families. Its larger-diameter profile holds the spur gear closer to the gear case, which reduces vibration and helps maintain consistent mesh under lateral loads typical in drifting.

This positioning also lessens sideways stress on the top shaft during sudden throttle inputs, contributing to a more immediate and predictable acceleration feel. The hub's shape is intended to improve spur retention and to deliver smoother rotation with fewer harsh impulses.

When installing the RD-630P in place of the series-standard spur gear hubs (for example Y4-630A, Y2-630PA, Y2-630RA), note that the set-screw location differs from those standard hubs. Replacing the hub may require the matching aluminum top shaft RD-631 to align the screw fixing position correctly.

Use the RD-630P when you want a larger-diameter hub that improves spur stability and reduces vibration; verify top-shaft compatibility and consider the RD-631 aluminum top shaft if the set-screw alignment differs.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this hub fit my RD-series chassis without modification?

It fits the listed RD/SD/MD chassis, but check set-screw alignment; some standard top shafts may need replacement with RD-631.

Does the hub change gear spacing or mesh?

The hub positions the spur closer to the gear case which can alter mesh slightly; verify mesh during installation and adjust as needed.

Is a special top shaft required?

When replacing certain standard hubs, the set-screw position differs and the aluminum top shaft RD-631 may be required for correct attachment.

What performance change should I expect after fitting this hub?

Expect improved spur retention and reduced vibration, which helps with smoother rotation and a more direct throttle response in drifting conditions.
