Refined Suspension Control from Yokomo B12-S3S

The Yokomo B12-S3S aluminium spring cup is designed for the BD12 chassis to refine suspension behaviour and improve track stability. A centrally mounted bearing reduces spring twisting during shock strokes, yielding a steadier and more linear repulsive response. Drivers can expect cleaner handling and more confidence entering corners.

Compatibility and What's Included

This spring cup fits a number of Yokomo designs, notably MSR-BD12, MSR-010, and MSR-010A. The package contains two pieces, making it convenient for routine maintenance or as an upgrade pair.
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 does an aluminium cup compare to plastic versions?

Aluminium cups offer greater dimensional stability and, with the bearing, reduce unwanted spring rotation compared with typical plastic cups, which can flex under load.

Will this affect the car's balance or weight much?

Any weight change is minimal, but the main effect is a more controlled spring action which can improve balance and predictability rather than significantly altering overall weight distribution.

How can I confirm compatibility before buying?

Check that your chassis is listed among the compatible models: MSR-BD12, MSR-010, and MSR-010A. If those match your build, the cup will replace the existing spring cup position without modification.
