13mm Shock Internal Spacer for RC Dampers - Serpent 500899  [SER500899]

Adjust internal volume with a 13mm spacer

The Serpent SER500899 13mm internal spacer installs inside a 13mm shock body to alter oil volume and change the damper's response. By redistributing internal space the spacer affects oil flow and effective travel margins so you can tune damping without swapping external parts.

For installation, service the shock by draining and disassembling it, fit the spacer in the correct position for your shock design, then reassemble and bleed the unit following the shock maker's procedure. Inspect seals and the shock shaft for wear while rebuilding to keep damping consistent and reliable.

Small spacer changes are a practical way to tweak low-speed and mid-speed damping, influence rebound characteristics, and adjust how the suspension uses its travel. Use spacer adjustments together with measured oil weights and spring choices to reach the handling balance you want for your RC model and track conditions.

Carry spare seals and a basic shock toolkit when you work with internal spacers, and run incremental track tests after each change to confirm effects on handling.
