Improve S411 Drivetrain Performance with Serpent 401633

The Serpent 401633 Aluminum 19T Mid Pulley is tailored for the S411 chassis to offer a robust replacement or upgrade option. Precision-machined from aluminium, it improves resistance to wear and keeps power delivery consistent during competitive running.

Robust Machining for Consistent Results

Made from premium aluminium, the Serpent 401633 mid pulley reduces the risk of premature wear while maintaining low rotational inertia. That combination supports stable acceleration and reliable performance over multiple race heats.

Accurate Fitment and Quick Replacement

Specifically produced for the Serpent S411 chassis, this 19T pulley installs cleanly without adjustments. It is an easy plug-in replacement for worn pulleys or a straightforward upgrade for those wanting improved drivetrain durability.

Is the pulley compatible with standard S411 belt sizes?

Yes, the Serpent 401633 matches the S411 belt and pulley standards. Always double-check belt width and routing when combining different aftermarket parts.

Will aluminium affect gear wear on other drivetrain parts?

Aluminium is harder than many plastics, so it can reduce wear on the pulley itself. Monitor mating components for any unusual wear patterns when switching materials.

Can I use this pulley for practice and race days?

Absolutely. The Serpent 401633 is suitable for both practice sessions and competition, offering consistent operation and longer service life compared with most stock plastic pulleys.

Any setup tips after fitting?

After fitting, check belt tension and run the car at low speed to confirm there is no binding. Recheck fastener tightness after the first few runs.
