Fine-Tuned Drivetrain Performance for 9XX

The Serpent 903809 aluminium 28T oneway differential pulley is a precision upgrade for 9XX series cars. Machined from solid aluminium, it smooths power delivery and improves drivetrain reliability during demanding track use.

Balanced Torque for Smoother Handling

The 28-tooth configuration spreads torque evenly through the driveline, helping to reduce wear on gears and bearings. Whether you are preparing for a race or refreshing an older car, this pulley supports more consistent handling and longer service intervals.

Specifications

A straight-forward upgrade for hobbyists and racers who want better drivetrain feel and increased durability without adding unnecessary weight.

Will this pulley fit every 9XX variant?

This pulley is designed for the Serpent 9XX series. Check your chassis parts list or measure the existing pulley to confirm fit for specific submodels.

What tools are needed to install it?

Installation typically requires common hobby tools such as hex drivers and a wrench. A light application of threadlocker on set screws can help prevent loosening.
