Serpent 421011 S240 Series Differential Balls  [SER421011]

Smooth Service and Reliability for Your S240 with Serpent 421011

If you keep your RC pans in top order, the Serpent 421011 Differential Balls are a worthwhile replacement part. Made with the S240 Electric Pancar in mind, these balls help the differential run cleanly for dependable performance during both practice and race sessions.

Engineered to Reduce Friction

The balls are manufactured to give smooth rotation and long life under normal use. Swapping worn balls for new Serpent 421011 parts reduces internal friction and wear in the differential housing, which supports more predictable handling and crisper responses on track.

Fitment and Typical Applications

These parts are intended for the Serpent S100, S120, and S240 lineups and serve as direct replacements for routine maintenance. They are suited to hobbyists and racers who want to preserve their pancar's handling characteristics without major changes to the drivetrain.
