Performance-oriented RD-630P spur hub

The RD-630P is a lightweight spur gear hub crafted to replace original units on Yokomo RD, SD, and MD drift chassis. By using a larger-diameter profile the spur sits closer to the gear case, which cuts vibration and helps keep mesh stable when the car is slid sideways.

This closer positioning reduces sideways loading on the top shaft during sharp throttle inputs, yielding a more immediate acceleration feel. The hub contour promotes better spur retention and smoother rotational behavior with fewer abrupt impulses.

Installing the RD-630P in lieu of series-standard spur hubs (for example Y4-630A, Y2-630PA, Y2-630RA) requires attention to set-screw placement, as it differs from the stock hubs. The RD-631 aluminum top shaft is the correct match if you need to realign the screw fixing position.

Use the RD-630P to tune for reduced vibration and crisper throttle reaction; double-check set-screw alignment and fit the RD-631 top shaft where needed to secure the hub properly.
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.

How does the RD-630P change throttle feedback during slides?

The hub's reduced vibration and closer spur placement produce a more direct transfer of throttle inputs, giving cleaner, faster throttle response when exiting a drift.

Will this affect corner-to-corner consistency?

Stabilising the spur position helps maintain mesh under lateral loads, which can improve consistency between runs and reduce unpredictable behaviour during quick transitions.

Should I alter gear spacing after fitting?

Because the hub positions the spur closer to the case, verify gear spacing and adjust as needed to ensure quiet engagement and correct backlash.

Any tips for setup when using the RD-630P?

Check set-screw alignment, confirm top-shaft fit (use RD-631 if required), and test mesh under lateral load to dial in the smoothest rotation and throttle feel.
