Clean Airflow Solution for the Serpent 960

The 51T solid axle pulley gives Serpent 960 owners a simple way to reduce rear-end aerodynamic drag. As a replacement rear pulley with a rib-free face, it can produce an approximate 3km/h increase in top speed when combined with suitable gearing and conditions.

Smooth Face for Less Turbulence

The pulley is built with a flat, disc-like exterior to minimise turbulent airflow. Removing ribs and protrusions means the pulley encounters less aerodynamic resistance and can spin more freely, supporting higher peak speed and steadier rotations.

Will this work in vintage racing classes?

It is suited to vintage and classic RC cars where period-correct parts are allowed, providing an aerodynamic benefit without altering core drivetrain geometry.

Is special tooling required to fit it?

No special tools are needed beyond standard hobby tools; ensure correct seating and check for runout after fitting.

How does it affect maintenance needs?

Maintenance remains routine: inspect the pulley for wear, confirm it stays true, and keep drivetrain parts clean to preserve the top speed advantage.

Can I try it on other models with similar specs?

Possibly, but it is specifically designed for the Serpent 960 series. Check axle diameter and spline fit before using it on different vehicles.
