Precision Pinion for the Eryx 411 4.1 Touring Car

The Serpent 120171 Aluminum Pinion Gear is intended to sharpen the Eryx 411 4.1's drivetrain. With 32 teeth at 48 pitch, the hard-aluminium construction balances durability with lower inertia. This pinion is aimed at enthusiasts who want cleaner gear engagement and improved throttle response.

Why Hard Aluminum Works Well

Hard aluminium offers a favourable strength to weight ratio that helps maintain acceleration without overly increasing rotating mass. The robust machining on this pinion supports smooth meshing and consistent tooth contact under load.

Fitment Notes for Easy Installation

Designed to match the Serpent Eryx 411 4.1 specification, this pinion fits directly when you use the correct shaft size and mounting hardware. The precise cut makes aligning the gear straightforward, helping reduce setup time at the track.

Is special maintenance required for aluminium pinions?

Routine inspection for tooth wear and ensuring proper lubrication of the spur gear are recommended. Aluminium may show wear faster than steel, so check tooth profiles regularly if you run high power.

What pitch and tooth count should I match?

Match the 48P pitch and 32T tooth count to your existing spur gear and motor shaft. Using the correct pitch ensures proper meshing and avoids premature wear.

Will using this pinion change my gearing ratio?

Gearing ratio depends on the combination of pinion and spur. This 32T pinion will alter final drive compared to different tooth counts, so choose based on track layout and motor characteristics.
