Mini Spyder Monster truck SER440001 Steering Pivot Ball 4.8x5.2x2.2mm - Serpent 440152  [SER440152]

Mini Spyder pivot replacement part

This Serpent 440152 pivot ball measures 4.8x5.2x2.2mm and serves as a replacement pivot for steering and suspension linkages on the Mini Spyder Monster truck RTR EP SER440001. It provides the small-diameter articulation the chassis expects where low play is important.

Use this part only with the Mini Spyder Monster truck RTR EP SER440001 noted in the product listing; if fitting to other models, confirm the physical dimensions and mounting arrangement first. The listed measurements refer to the component outer profile and seating envelope, so check clearances before committing to fitment.

Fitment tips: remove the relevant wheels and disconnect steering links to expose the pivot seat, inspect mating parts for wear, press the pivot ball squarely into place, and reassemble using original fasteners. Recheck steering alignment and make minor trim adjustments to toe as required after installation.

On-track effect: replacing tired pivot balls tightens steering feel and maintains consistent suspension pivot points, which stabilizes handling during acceleration and cornering.
