Y4-630A Spur Hub by Yokomo

The Yokomo Y4-630A Aluminum Spur Gear Hub fits the YD-2 and YD-4 series and is CNC-machined from black anodized aluminum to offer a stiff yet light mounting point. It clamps the spur to the main shaft to maintain alignment under load, which supports consistent drive characteristics.

Metal vs Plastic Spur Hubs

Choosing an aluminum hub reduces rotational weight while providing a firmer interface than plastic. The anodized finish boosts abrasion resistance and helps preserve the seating surface for the spur gear, leading to steadier throttle transitions and less slop.

Compatibility Details and Setup

Designed for direct replacement on Yokomo YD-2 and YD-4 cars, the Y4-630A installs without major modification. After installation, verify set screw tightness and gear mesh to ensure the hub performs reliably on track sessions.
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 if I run a different spur thickness?

The hub accepts standard spur thicknesses used on YD-2 and YD-4 setups, but confirm the spur face width matches the hub seating to avoid lateral play.

How often should I check the clamp screws?

Check clamp screws after the first few runs and periodically thereafter, especially after impacts, to keep the hub secure and aligned.

Can this hub be used with high torque motors?

Yes, the machined aluminum construction handles higher torque loads better than stock plastic hubs, but always monitor wear when using powerful setups.
