13mm Shock Piston Blank Compatible with 13mm Shocks - Serpent SER500900  [SER500900]

13mm shock piston component

This Serpent SER500900 Shock 13mm piston blank is designed as a neutral piston part for 13mm shock absorbers in RC model dampers. It provides a simple flow profile intended to work with appropriate shock bodies and shim stacks to shape damping characteristics.

Compatibility: specified for shock systems with a 13mm internal diameter; ensure this blank is matched to shock oil grade, shaft dimensions, and any piston hole or shim configurations you plan to use. Always confirm measurements before assuming fit with other setups.

Installation notes: remove any machining residue before fitting, maintain identical orientation for pistons across the same vehicle, and use correct O-rings and retaining hardware. After filling, cycle the damper to expel air and check smooth shaft action before track or field use.

Tuning role: as a baseline piston the blank dictates a starting flow characteristic; introducing ported pistons or adjusting shim stacks will change compression and rebound. Employ the blank when testing incremental valving changes or when you need to cap flow for higher damping forces.

A practical baseline piston for damper development and when assembling bespoke piston and shim combinations.
