Serpent SER411449 30mm Damper Extension S120 PRO Handling Upgrade  [SER411449]

Setup Notes for Serpent 30mm Damper Extension

The Serpent SER411449 Damper Extension 30mm is a straightforward accessory that alters suspension geometry to refine handling on your RC car. Made for the S120 PRO, it gives racers an accessible way to tweak steering balance and mid-corner behaviour.

Compatibility and Expected Effects

This 30mm extension is designed to replace the 10mm extension used in cars such as the F110 SF4 (SER411394). Extending the damper length increases on-power steering response, which can help with rotation and corner entry, but it can also reduce rear stability during heavy braking.

Finding the Right Balance

If you need a more planted rear end, removing the extension returns a more neutral behaviour under acceleration and braking. The part is useful for drivers who regularly adjust their setup to match grip levels or driving style.
