Durable Aluminium Pinion for Eryx 411

Model builders aiming to sharpen drivetrain reliability on the Serpent Eryx 411 will find the Serpent 120170 aluminium motor pinion a solid choice. Manufactured to tight tolerances, it supports consistent tooth mesh for track day or club racing sessions.

Why the 48P/31T Matters

The Serpent 120170 uses a 48-pitch 31-tooth form to deliver steady power transfer and reduced backlash. The hardened aluminium construction cuts mass while improving resistance to routine wear, helping keep running characteristics stable.

Fitment Notes and Typical Use

This pinion fits the Serpent Eryx 411 4.1 Touring Car EP as a direct replacement with no modification needed. It is suitable for routine maintenance swaps or as an upgrade when preparing the car for competitive runs.

Is installation difficult for club racers?

Installation is straightforward for most hobbyists. Set pinion mesh carefully, secure fastenings, and spin the drivetrain by hand to confirm correct engagement before full power runs.

What electronics pair well with this pinion?

This pinion works with standard brushless setups used on the Eryx 411. Match motor timing and ESC settings to your setup and verify gear mesh under load for best results.

How should I check for wear?

Inspect teeth for rounding, burrs or repeated deformation after heavy sessions. Clean out trapped debris and replace the pinion if tooth profiles show clear damage.

Will aluminium change handling feel?

Any weight change is minimal, but the firmer tooth engagement from a precision pinion can deliver crisper throttle response and more consistent drive characteristics.
