Notable Details for the Serpent 120125

Material: Built from durable aluminum to keep weight down while holding up to racing stress.
Compatibility: Specifically matched to the Eryx 411 4.1 Touring Car for correct fit and mesh geometry.
Tooth Count: 38T, 64 pitch for smooth interaction with compatible spur gears.

Will this pinion change my overall gear ratio significantly?

Changing to a 38T pinion alters the final ratio based on your current spur size. Calculate teeth differences to predict top speed and acceleration trade offs before swapping.

Is the mounting robust for frequent gear changes?

The pinion is designed for repeated fitting, but use a good quality set screw and check tightness after initial runs to avoid slippage on the motor shaft.

What checks should I do after first installation?

After installing, confirm mesh clearance, run the car at low speed to listen for noise, and re-tighten the pinion set screw. Inspect teeth for correct seating.
