On-Track Upgrade for BD9

The Yokomo B9-501MCAA aluminium spool drive cup is tailored for the BD9 chassis, offering a lighter alternative to steel that helps the drivetrain accelerate more responsively during racing sessions.

Advantages of Aluminium Spool Parts

Aluminium parts lower inertia without losing strength, which helps with quicker throttle recovery and improved mid-corner transitions when paired with a tuned setup.

Fitment Overview

This drive cup is suitable for a number of Yokomo models, including MSR-010, MRTC-BD919, and MRTC-BD11 series, allowing it to be used across different BD9-based assemblies.
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 require changes to my gear mesh?

No major changes are needed, but verify gear mesh after swapping parts to ensure smooth engagement and to prevent premature wear.

Will it make the car feel more twitchy?

You may notice crisper throttle response; tune your diff and suspension if the extra responsiveness requires balance adjustments for stability.

Is thread locker recommended on fasteners?

Light thread locker on steel-to-steel fasteners is useful to prevent loosening, but follow the manufacturer's guidance to avoid overuse on aluminium threads.
