Fit the Serpent 421063 11T Pinion to Your S240

The Serpent 421063 Pinion 11T is a precision component engineered to bring reliable gear engagement to S240 electric pancars. Its accurate machining helps maintain consistent contact with the spur gear under race conditions.

Features That Matter on Track

Tailored for the S240 range, the 11T option offers a controlled ratio that balances acceleration with top speed. The construction focuses on wear resistance so it keeps its profile through repeated heats.

Why Experienced Drivers Choose This Pinion

Experienced RC drivers appreciate the Serpent 11T for its predictable mesh and reduced drivetrain strain. It is a straightforward upgrade for those tuning gear ratios for different track layouts.

Will this pinion affect top speed?

Changing tooth count alters final drive ratio, so fitting an 11T will influence top speed depending on your spur gear and motor choice. Use gearing charts to predict changes.

Can I run this in wet or dusty conditions?

The material is durable but exposure to water and grit accelerates wear. Rinse and dry components after wet runs and keep debris out of the gear mesh to prolong life.

Is professional reaming required for fit?

Most installations are straightforward without specialist machining, but confirm bore size and shaft fit. Some users prefer a light ream for a perfect press fit if tolerances demand it.

How often should I carry a spare pinion?

Carry at least one spare at race meetings, especially if you change gears often or run on abrasive surfaces. Quick swaps keep you on track with minimal downtime.

Does this pinion come in other tooth counts?

Serpent and third party suppliers offer alternate tooth counts for different gearing needs. Verify compatibility with your spur gear before selecting a different size.
