Track Tuning with Yokomo 1.1mm Piston

The Yokomo B9-S114A piston is intended for BD9 high big bore short shocks and features four 1.1mm openings to control oil flow. That stable flow helps drivers tweak handling characteristics for different track conditions.

Fitment and Compatibility

This piston is compatible with a range of Yokomo chassis, including MRTC-BD10, MRTC-BD10A and MRTC-BD10LC among others. It allows for quick integration into existing shock rebuilds and tuning sessions.
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.

Can this piston help with understeer or oversteer?

Adjusting piston and oil combinations affects roll and weight transfer; use the B9-S114A to fine-tune front or rear damping as part of a broader setup change.

Do I need special tools to swap pistons?

Basic shock tools and a clean workspace are sufficient; handle small parts carefully and follow standard shock rebuild steps.

Should I change springs when changing pistons?

Spring choice is part of overall setup. You may keep springs but expect handling shifts when you alter internal damping, so test and adjust as needed.
