Medius X26 Pivot Balls Upgrade Kit (Aluminium) - SER402189 by Serpent  [SER402189]

Upgrade components for pivot mounts

This Serpent SER402189 pivot ball set supplies four aluminium pivot balls intended for RC-scale suspension and steering pivot points. The parts are a direct match to the Medius X26 naming present in the product reference, and are intended for use on the referenced Medius X26 steel EP (SER400052) chassis configuration.

The components are supplied as machined aluminium pivot balls in a pack of 4 pcs, designed to replace or upgrade existing pivot joints where aluminium pivot balls are specified. In practical setup work they serve as the rotating contact in steering knuckles and suspension link mounts, where material choice affects wear characteristics and setup feel.

Installation notes: confirm the existing pivot housings and retaining hardware are compatible with aluminium balls, clean contact surfaces before assembly, and verify free rotation and secure retention at final torque settings. During tuning, swapping to aluminium pivot balls can slightly change friction and feedback compared with steel or composite alternatives, so re-check steering centering and toe settings after fitment.

For racers and tinkerers running a Medius X26 chassis, the SER402189 aluminium pivot ball kit is a simple swap or upgrade; always validate clearance and movement after installation.
