Serpent SER500917 Green 13mm Rear Spring 2.4lbs  [SER500917]

Spring specification overview

The Serpent SER500917 is a dedicated RC rear shock coil, identified by the product code and supplied in green with a nominal 13mm diameter and a labeled 2.4lbs spring rate. It is offered as a replacement coil for rear shocks of the matching size and should be used as a tuning element, not as a full shock assembly.

Installation steps are standard: remove the shock cap, withdraw the spring retainer, slide the spring onto the shaft, then reassemble and set preload to match both sides. After fitting inspect full compression and rebound clearance and retorque fittings after a short shakedown run.

When used for tuning the spring alters rear ride height and compression resistance, which affects traction and corner behaviour. Combine spring changes with damper adjustments and tyre selection, making incremental swaps to evaluate the handling impact.
