Lightweight Drive Cup for BD9 Chassis

The Yokomo B9-501MCAA spool drive cup is crafted for BD9 platforms to replace heavier steel components, lowering rotating mass and sharpening throttle control for more reactive on-track behaviour.

Why Aluminium Works Well on Track

Aluminium balances durability with reduced weight so your car accelerates quicker and responds better to driver inputs, while still standing up to regular racing use if inspected routinely.

Models and Applications

This part is compatible with several Yokomo models, such as MSR-010, MRTC-BD919, and MRTC-BD11 series, making it a versatile option for racers updating BD9-derived cars.
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.

How hard is the install for a club racer?

Installation is straightforward with basic tools; remove the old cup, confirm spline alignment and torque fasteners to the chassis manual to avoid play.

Will this affect handling on different surfaces?

Reducing rotating mass improves response across tarmac and carpet; suspension and tyre choice will still be the main factors for surface-specific handling.

Any special maintenance for aluminium parts?

Inspect for burrs or wear after heavy use, keep mating surfaces clean and ensure fasteners remain tight to preserve performance.
