Sharper Damping with Yokomo S4-S202-25 Pistons

The Yokomo S4-S202-25 pistons are 2.5mm thick components built for 13mm shock assemblies to improve damping accuracy and setup repeatability. These pistons can help you achieve more consistent handling and are compatible with the SOR-030 and MOR-020 chassis, whether for maintenance or performance tuning.

Design Details for Tuners

With a 2.0mm x 2-hole configuration, the S4-S202-25 pistons control oil passage to refine compression and rebound behaviour. This allows tuners to target specific handling traits across different surfaces, and the parts are made to withstand frequent use.

Compatibility Notes

These pistons are matched to Yokomo SOR-030 and MOR-020 chassis. They make a good upgrade for drivers replacing aged pistons or those wanting clearer feedback from their suspension setup.
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 should I test these pistons on track?

Start with your usual shock oil, then try softer and firmer oils to observe changes in midstroke and rebound. Make small changes and log results.

Are special tools needed to fit these pistons?

No specialised tools are required beyond common shock service tools and a clean work area to avoid contaminating oil.

Will these pistons work with different spring rates?

Yes, they work independently of spring rate; combine piston choice with spring and oil changes to tune overall suspension feel.
