Serpent 120157 - 48P 19T Aluminum Pinion Gear, Track Ready  [SER120157]

Upgrade your drivetrain with the Serpent 120157 pinion

The Serpent 120157 is an aluminum 48P 19T pinion gear engineered for serious RC hobbyists. Its precise 48-pitch cut and 19-tooth profile make it a durable choice for 1/10 scale vehicles where a tight fit and consistent engagement matter.

Advantages of an aluminum pinion

Aluminum pinions like the Serpent 120157 reduce rotating mass compared to heavier materials, which can help throttle response and smooth acceleration. The hard anodized surface increases abrasion resistance so the gear holds up well under regular track use.

Compatibility and tuning notes

With its 48P pitch and 19T count, this pinion suits a wide range of 1/10 scale setups. Use careful mesh adjustment to balance speed and torque, and verify fitment on your specific gearbox before running.
