Serpent SER500900 Shock Piston Blank 13mm  [SER500900]

Blank piston for 13 mm dampers

This Serpent SER500900 Shock 13mm piston blank is a straightforward piston intended for 13mm shock absorbers in model car dampers. It functions as a base piston to be used alongside matching shock bodies and shim stacks to influence fluid flow and damping traits.

Compatibility: made for 13mm internal-diameter shock assemblies; match the piston to your planned shock oil, shaft diameter, and piston hole or shim setup when tuning. Confirm physical dimensions before fitting to systems that are not specified as 13mm.

Installation notes: inspect the component for any machining debris before installing, place the piston with consistent orientation in each damper, and fit the proper O-rings and retention hardware. After assembly, cycle the shock to remove trapped air and ensure smooth shaft operation before use.

Tuning role: the blank gives a neutral flow starting point; swapping to drilled or ported pistons or changing shim stacks alters compression and rebound. Keep the blank on hand for controlled comparisons when adjusting valving or increasing flow resistance.

A useful basic piston for damper tuning cycles and for building tailored piston configurations.
