Tune Shocks Precisely with Yokomo S4-SB1320

The Yokomo S4-SB1320 blank piston is designed for 13mm shock assemblies and lets you create bespoke hole patterns to adjust flow characteristics. Guide marks make it easy to lay out between two and six holes for consistent drilling.

Adjust Flow for Track Conditions

Available in 1.5mm, 2.0mm, and 2.5mm thicknesses, this piston lets you tune firmness. Softer setups favour smaller thickness and more holes, while fewer holes and thicker pistons give firmer damping for rougher tracks.

Compatibility and Installation Advice

This blank piston suits several Yokomo models such as SOR-020, MOR-020, and SOR-020D. Installation is straightforward and works well as part of a shock rebuild or when refining suspension performance.
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 many holes should I try first?

Begin with three holes as a baseline and adjust from there based on how the car feels on your usual surface.

Will drilling change oil flow significantly?

Yes, hole size and number alter flow. More or larger holes reduce damping resistance, so make incremental changes and log results.

What drill bits work best?

Use small, sharp bits designed for metal such as HSS micro bits. A hand drill or rotary tool with a steady rest helps keep holes straight.

Is this piston compatible with standard Yokomo shocks?

Yes, it is compatible with several Yokomo off-road chassis listed like SOR-020, MOR-020, and SOR-020D, but always check fit before final assembly.
