Serpent 440132 Replacement Pivot Pin for Mini Spyder SER440001  [SER440132]

Pivot pin function on the Mini Spyder

This RC-scale pivot pin is supplied as a direct spare for the Serpent Mini Spyder Monster truck RTR EP (SER440001). It acts as the articulation point in steering and suspension link assemblies, restoring correct movement where wear or play has developed on the chassis.

Fitting is straightforward for hobbyists familiar with routine teardown: remove the wheel and hub to access the control arm, inspect adjacent parts such as bearings and linkage hardware for wear, swap the worn pin for the replacement, and confirm free movement without binding. Reuse the vehicle’s original fasteners and retainers during reassembly.

During setup and maintenance, a serviceable pivot pin helps maintain steering geometry and reduces unwanted slop that degrades handling. Replacing a worn pivot pin is a common repair that can bring back predictable steering feel and more consistent lap-to-lap performance.
