Precision Piston Blank for 13mm Shocks - Yokomo S4-SB1325

Ideal for club racers and tuners, the Yokomo S4-SB1325 blank piston fits 13mm SO/MO shock absorbers and has a 2.5mm wall thickness. The marked piston face assists accurate drilling of 2 to 6 holes with a pin vise so you can adjust damping behaviour for differing circuits and surfaces.
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.

Which chassis models suit this piston?

This piston is compatible with the SOR-020, MOR-020 and SOR-020D chassis variants.

How should I approach choosing hole count?

Select a hole count within the 2 to 6 range and evaluate on-track. Altering hole number changes internal flow so try incremental changes and record results.

Do I need to finish the piston after drilling?

Yes, remove any burrs and wash the piston to clear debris before installing. Clean assembly prevents oil contamination and ensures consistent damping.
