Lightweight Aluminium Pinion by Serpent SER120177

The Serpent SER120177 48P 39T aluminium motor pinion is designed for enthusiasts who value precise gear engagement. It is compatible with many electric motor setups and helps keep drivetrain behaviour consistent.

Reasons to Choose Aluminium

Aluminium pinions reduce rotating mass while providing solid tooth strength for normal hobby use. That combination supports smoother acceleration and predictable gear meshing during runs.

Suitable Vehicles and Applications

This 48 pitch, 39 tooth pinion fits a broad range of electric cars, making it useful for track tuning or casual driving. It allows for fine adjustments to gearing without introducing excessive weight.

Can I swap a steel pinion for this aluminium one?

In many setups you can replace a steel pinion with this aluminium option if the pitch and shaft fit match. Check gear clearance and inspect for wear more frequently.

Is this pinion suitable for high power builds?

Aluminium suits routine hobby and club level power, but very high power or extreme torque applications may benefit from hardened steel pinions. Consider your motor output and driving style when choosing.

How do I keep the pinion performing well?

Keep the pinion free of grit, confirm correct mesh, and tighten the fixing screw correctly. Replace the pinion if you detect rounded or damaged teeth.
