Serpent 500899 Shock 13mm Internal Spacer  [SER500899]

13mm shock internal spacer for damper tuning

This Serpent SER500899 13mm internal spacer is an RC-scale damper component intended to change the internal volume and response characteristics of compatible shock absorbers. Used inside a 13mm shock body, the spacer alters oil flow and effective travel margins so drivers can fine-tune damping feel without changing external components.

Installation is straightforward for experienced model builders: drain and disassemble the shock, place the spacer inside the shock body or around the shaft as required by the shock design, then reassemble and bleed the unit following the shock manufacturer's service practice. Always inspect seals and the shock shaft for wear when reassembling to maintain reliable damping behavior.

In tuning, small changes to internal spacers are useful for dialing low-speed and mid-speed damping feel, adjusting rebound characteristics, and tuning how the suspension uses available travel. Combine spacer changes with measured oil weights and spring rates to reach the desired handling balance for your RC model and track conditions.

Keep spare seals and a small toolkit when working with internal spacers, and perform test runs after each incremental change to confirm the effect on handling.
