Stability Upgrade for BD12: Yokomo B12-S3S

The Yokomo B12-S3S aluminum spring cup is precisely machined for the BD12 chassis, delivering improved stability and more controlled suspension action. A bearing fitted in the centre reduces spring rotation during shock travel, producing a more linear and repeatable repulsive force. This translates to a steadier car and sharper cornering for competitive runs.

Fitment and Package Contents

This spring cup is compatible with several Yokomo chassis including MSR-BD12, MSR-010, and MSR-010A. The box contains two pieces, making it a straightforward upgrade or a direct replacement to keep performance consistent.
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 the central bearing affect suspension feel?

The bearing centres the spring and prevents it from twisting during shock compression, which helps the suspension move more smoothly and predictably through its stroke.

Will this fit my BD12 chassis without modification?

Yes, it is designed for BD12-series builds and also fits MSR-BD12, MSR-010, and MSR-010A as listed, so it installs as a like-for-like swap on compatible shocks.

What maintenance does the bearing need?

Keep the bearing free of grit and apply light lubricant when needed. Inspect for smooth rotation periodically and replace if it feels rough or binds.
