Yokomo YOKBDS103 1mm 3-Hole Damper Piston for R/C Shocks  [YOKBDS103]

1mm Three-Hole Damper Piston Overview

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.

Install it as you would any internal piston: ensure the piston slides freely on the shock shaft, orient the holes consistently between front and rear shocks, and use compatible shock oil and seals. This component is a simple, low-cost option to change the damper's hydraulic characteristics without replacing the entire shock assembly.

Tuning notes: three holes provide a different flow profile compared with single- or two-hole pistons, which affects rebound and compression balance. Try incremental changes in oil viscosity and piston selection when chasing consistent handling across a run.
