Overview of the 3-Hole 1mm Piston

This Yokomo YOKBDS103 3 hole piston is an RC-scale damper part intended for use inside shock bodies to alter oil flow and damping behaviour. The 1mm three-hole pattern offers a specific bleed characteristic useful when refining mid-to-high speed damper response during setup.

Fitting notes: ensure the piston is free on the shock shaft, keep the hole alignment consistent on both ends of the car, and use matching shock oil and seals. The piston is a cost-effective way to tailor hydraulic damping without swapping entire shock assemblies.

Selection advice: three-hole pistons produce a different hydraulic profile than one- or two-hole options, which changes the rebound/compression tradeoff. Combine piston choice with incremental oil adjustments to fine-tune corner entry and exit 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.

Will this piston work with stock shock bodies?

In most cases the YOKBDS103 fits standard RC shock assemblies that accept internal pistons; verify shaft diameter and internal spacing before installing.

How do I choose between 1, 2, and 3-hole pistons?

Choose based on desired damping feel: single-hole for firm, low-bleed behaviour, two-hole for a middle ground, and three-hole for increased flow; then tune oil viscosity to balance handling.
