Yokomo Y4-630A Spur Hub Upgrade

The Yokomo Y4-630A Aluminum Spur Gear Hub is tailored for YD-2 and YD-4 chassis, milled from black anodized aluminum to deliver a robust yet lightweight connection. It mounts to the spur and main shaft to secure gear engagement during aggressive acceleration.

Advantages of an Aluminum Hub

Aluminum hubs are favoured for their combination of toughness and low mass, which cuts down on rotational inertia. The anodized coating gives extra wear resistance and helps maintain a stable contact surface between the hub and spur, improving drivetrain feel.

Fit and Fitment Advice

Built for direct compatibility with Yokomo YD-2 and YD-4 cars, this hub replaces stock plastic parts without major setup changes. After fitting, check gear mesh and clamp screw torque to ensure reliable performance in varied running conditions.
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.

Does this improve drivetrain reliability?

The metal hub resists deformation better than plastic, so it tends to keep the spur seated correctly under load, which improves reliability.

Should I change gear mesh after fitting?

Yes, always recheck and fine tune the gear mesh after installing a new hub to prevent binding and excessive wear.

Is special grease required for the hub?

No special grease is needed on the hub itself, but keep bearings and gears lubricated per normal maintenance to protect the drivetrain.
