Lightweight aluminium pinion for precise gearing

The Serpent SER120178 Motor-pinion is a practical upgrade for modellers wanting consistent gear engagement. Constructed from aluminium, this hard 48P, 40T pinion gives predictable performance across a variety of RC applications.

Consistent power delivery under load

For hobbyists focusing on setup and control, the Serpent motor pinion delivers smooth power transfer and steady tooth contact. Its build quality helps reduce surprises from intermittent gear slipping.

Good fit for common RC platforms

Designed to work with many 48P-compatible vehicles, this pinion is an easy replacement when refreshing drivetrain components or experimenting with gearing choices for handling and speed tuning.

Which models typically use a 48P pinion like this?

Many 1/10 scale kits and RTR cars that specify 48P gearing can accept this pinion, but confirm your spur gear pitch first.

How should I check motor shaft compatibility?

Measure your motor shaft diameter and compare with the pinion bore; you may need a suitable grub screw or adapter depending on the shaft type.

Is aluminium easy to service compared with steel pinions?

Aluminium is easier to machine and replace, and with correct mesh and cleaning it provides a reliable service life for regular hobby use.
