Upgrade Your Eryx 411 4.1 Drivetrain with a Strong Pinion

The Serpent 120171 Aluminum Pinion Gear is made to enhance the Eryx 411 4.1 Touring Car EP. With 32 teeth and a 48 pitch, the hard aluminium construction combines toughness with reduced weight to support responsive acceleration. This pinion is a sensible upgrade for club racers and weekend drivers alike.

Material Benefits for Track Use

Hard aluminium offers a reliable compromise between durability and lightness, helping to keep rotational inertia down while resisting typical wear from road conditions. The precision cut teeth improve engagement consistency at speed.

Installation and Compatibility Overview

Specifically produced for the Serpent Eryx 411 4.1 line, the pinion fits when matched to the correct motor shaft and clutch hardware. Accurate machining simplifies alignment so you can spend more time running and less time adjusting.

Can I swap this into older Eryx models?

It is built for the Eryx 411 4.1 specification, but it may fit older models that share the same shaft diameter and 48P spur gear. Verify measurements before swapping.

How should I secure the pinion to avoid slippage?

Use the correct set screw tightened to the motor shaft specifications and consider thread locker if you see repeated movement. Check alignment after a few runs to confirm it stays tight.

Are there upgrade options for longer life?

If you need greater longevity in very high-torque builds, consider hardened steel alternatives, but remember they add rotating mass which can affect responsiveness.
