Race-Proven Drive Cup Upgrade

The Yokomo B9-501MCAA aluminum spool drive cup is engineered for the BD9 chassis, replacing heavier steel parts to reduce rotating mass and deliver a more immediate throttle feel for competitive track use.

Benefits of Aluminum Components

Choosing aluminum gives you a strong yet lighter alternative to steel, helping acceleration and responsiveness without compromising part longevity when maintained correctly.

Compatibility and Fit

This drive cup fits a range of Yokomo chassis, including MSR-010, MRTC-BD919, and MRTC-BD11 series, making it a straightforward upgrade for many BD9-derived setups.
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 the Yokomo B9-501MCAA fit all BD9 variants?

It is compatible with most BD9 variants and the chassis listed, but always compare the part with your current drive cup to confirm fit before installation.

Should I replace bearings when fitting this cup?

You can reuse bearings in good condition, however swapping to fresh bearings of the same spec can minimise play and deliver the best drivetrain feel.

Any setup tips after installation?

Check gear mesh and drivetrain alignment, apply a small amount of thread locker to fasteners if needed, and run initial tests on a smooth surface to confirm responsiveness.
