Race-Ready Serpent 120179 Pinion for Eryx 411 Drivetrains

The Serpent 120179 Aluminum Motor Pinion Gear fits the Eryx 411 4.1 Touring Car EP and provides accurate gear engagement for competitive running. Its 48 pitch and 61 tooth layout supports reliable power delivery during aggressive driving.

Aluminum Build for Track Durability

Made from aluminium-grade material, the pinion balances robustness with low rotating mass to help both acceleration and handling response. Heat and wear resistance make it a solid track choice.

Tailored Compatibility with Eryx 411

Specifically designed to pair with the Eryx 411 series, the 120179 pinion sits correctly with the spur and gearbox to reduce slop and uneven wear, suitable for both maintenance swaps and performance upgrades.

How do I install the Serpent 120179 on my motor?

Slide the pinion onto the motor shaft, align it for correct mesh with the spur, then tighten the grub screw to the recommended torque. Verify the set screw clears any flat on the shaft for secure mounting.

What tuning changes are needed after fitting a new pinion?

Changing pinion size alters gear ratio, so you may need to adjust gearing choices for acceleration and top speed. Recheck mesh, motor temperature, and lap pace after the swap.

Are there benefits over a plastic pinion?

Aluminum pinions resist tooth deformation and generally last longer than plastic under high loads, offering more consistent performance for regular track use.

Will this pinion affect motor temperature?

Motor temperature is mainly influenced by gear ratio and load. Ensure proper mesh and gearing to avoid excessive motor strain; aluminium pinions themselves do not dramatically change heat characteristics.
