Lightweight Aluminium Pinion for Eryx 411

The Serpent 120124 Aluminium Motor Pinion Gear is specified for the Eryx 411 4.1 Touring Car with a 64P/37T tooth count. CNC finished from aluminium to keep weight down while retaining strong tooth geometry, it is a solid choice for crews looking to improve acceleration without sacrificing reliability.

Dialling In Drive Efficiency

With aluminium construction the Serpent 120124 reduces rotating mass for crisper throttle changes and smoother acceleration. The 64-pitch profile ensures reliable engagement with matching spur gears, making gear changes predictable across different track surfaces.

Can I use this pinion with other spur gear sizes?

Yes, you can pair it with various spur sizes so long as they are 64-pitch and the mesh is set correctly. Changing spur teeth alters final drive ratio.

How do I check the bore fit?

Measure the motor shaft diameter and compare with the pinion bore. If needed, use a light press fit or correct adaptor for a snug, wobble-free mounting.

Is aluminium prone to wear compared to steel?

Aluminium is lighter and can wear faster than steel under extreme loads, but for typical touring car use it offers a good trade-off between weight savings and service life.
