Performance Notes for RD-630BK

The RD-630BK is a lightweight spur gear hub developed for Yokomo RD, SD and MD drift chassis. By increasing diameter it raises the spur contact area, aiding rotation stability and decreasing vibration during steady driving and steering corrections.

The hub's nearer positioning of the spur gear to the gear case can lessen load on the top shaft under abrupt acceleration, yielding a more immediate drive response. Note that replacement of previous series-standard hubs such as Y4-630A, Y2-630PA, or Y2-630RA will reveal a different set-screw fixing location.

For those chassis that need the alternate fixing position, Yokomo recommends the RD-631 top shaft to ensure correct alignment of the set-screw and safe installation. The RD-630BK is intended as a tuning upgrade to improve spur engagement and drivetrain feedback, not to change gear ratios.

Installed as a drop-in hop-up on supported Yokomo drift chassis, the RD-630BK targets improved spur hold and lower vibration; use the RD-631 top shaft when replacing earlier hubs with a different set-screw location.

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.
The larger contact patch helps the spur gear hold under throttle and steering transitions, producing a firmer and more predictable drivetrain response during drifting maneuvers.
If your vehicle originally used hubs like Y4-630A, Y2-630PA, or Y2-630RA, the RD-630BK's set-screw position may not align. In those cases the RD-631 top shaft ensures correct screw placement and secure fitment.
The source information does not list included spur gears or bearings, so verify the seller's listing for what is supplied to avoid missing parts during installation.
After fitting, check set-screw torque, confirm gear mesh under load, and run a careful test to ensure vibration is reduced and engagement feels consistent.
