Adjustable Shock Piston for Yokomo S4-SB1320

The Yokomo S4-SB1320 blank piston fits 13mm shock bodies and gives you the freedom to create hole patterns that match your driving needs. Markings on the piston help you place between two and six holes with good repeatability.

Set Suspension Feel

Choose from 1.5mm, 2.0mm, and 2.5mm thicknesses to influence how soft or firm the shocks act. Thinner pistons yield a livelier response while thicker pistons stabilize the car under heavy impacts.

Where It Fits

This piston works with a number of Yokomo off-road models including SOR-020, MOR-020, and SOR-020D and is a practical upgrade for drivers looking to refine shock behaviour.
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 hole count affect handling?

More holes generally reduce damping, making the car more compliant. Fewer holes increase resistance and give a firmer ride for aggressive lines.

Which thickness is best for racing?

For tight, high-speed circuits you may prefer the 2.0mm or 2.5mm options for stability. Use 1.5mm when you need more feedback and suspension movement.

How should I maintain these pistons?

Keep pistons clean and free of burrs after drilling. Inspect for wear and replace if holes or edges become damaged to maintain consistent damping.
