Serpent SER500900 Shock 13mm piston blank  [SER500900]

13mm shock piston blank

This Serpent SER500900 Shock 13mm piston blank is an RC-scale piston blank intended for 13mm shock absorbers used in model car dampers. The blank is a basic piston element designed to be paired with compatible shock bodies and shims to alter fluid flow and fine-tune damping characteristics.

Compatibility: the part is intended for 13mm internal-diameter shock assemblies and should be matched to shock oil viscosity, shock shaft size, and piston hole arrangements when tuning. Do not assume compatibility with non‑13mm systems without checking physical dimensions.

Installation notes: inspect the piston blank for burrs before fitting, orient the piston consistently with other pistons in the same damper, and use the correct retaining hardware and O‑rings for your shock assembly. When reassembling, cycle the shock to expel air bubbles and verify smooth shaft movement before track use.

Tuning role: as a piston blank it provides a baseline flow profile; swapping it with drilled or ported pistons or combining it with shims changes compression and rebound response. Use the piston blank when experimenting with progressive valving setups or when you need to restrict flow to increase damping resistance.

This part serves as a basic piston element for RC dampers, useful during iterative shock setup and when building custom piston configurations.
