Refine Eryx 411 4.1 Drive Smoothness with a Precision Pinion

The Serpent 120171 Aluminum Pinion Gear is engineered to improve drivetrain behaviour in the Eryx 411 4.1 Touring Car EP. With a 32T count and 48P pitch, the hard aluminium construction provides a balance of durability and low weight to support reliable gear engagement. This part works well for those tuning their setup for consistent lap times.

Why Choose a Hard Aluminium Gear?

Hard aluminium gives a useful compromise between toughness and reduced inertia, which helps preserve acceleration while maintaining good wear properties when matched correctly. The precision machining promotes smooth contact with the spur gear under load.

Setup and Compatibility Notes

Made to fit the Serpent Eryx 411 4.1 specification, installation is straightforward when the motor shaft and mounting hardware match. Correct alignment and secure fastening are important to ensure dependable service during regular track use.

What checks should I perform after fitting the pinion?

After fitting, verify gear mesh, ensure the pinion set screw is tight, and run the car at low speed to listen for unusual noise. Reinspect after a few runs to confirm no loosening or abnormal wear.

Will aluminium affect motor temperatures?

The pinion material has minimal direct effect on motor temperature, but improved mesh can reduce friction heat. Always monitor motor temps in high-power setups and adjust gearing if necessary.

Is this pinion a direct swap for the stock part?

If your stock part shares the same 48P pitch and motor shaft dimensions, this Serpent 120171 will typically be a direct replacement. Double-check specifications before fitting to avoid mismatches.
