Serpent SER120123 Aluminium 64P 36T Hardened Pinion  [SER120123]

Reliable drivetrain upgrade for precise performance

The Serpent SER120123 is crafted to improve drivetrain efficiency for club racers and weekend builders alike. Made from hardened aluminium, this 64-pitch 36-tooth pinion reduces weight without sacrificing strength, helping your motor run cleaner and longer between maintenance intervals.

Advantages of an aluminium pinion

Aluminium pinions such as the Serpent SER120123 strike a practical balance between low mass and toughness. The lightness lowers rotating inertia on the motor shaft while the treated surface resists wear under frequent high-speed operation. That combination suits racers who want consistent, predictable gear engagement.

Vehicle fit and typical uses

This 64P 36T pinion works across many RC platforms, from on-road touring cars to lightweight buggies where fine tuning of gear ratios is common. Its tooth count and pitch give flexibility for adjustments aimed at either top speed or improved acceleration.
