Accurate gearing with Serpent 120139

The Serpent 120139 Aluminium Pinion Gear gives RC modelers a solid, lightweight option for improving drive train behaviour. Built from tough aluminium and cut to 64-pitch with 52 teeth, it helps maintain clean gear mesh and consistent performance across laps. Fit it when you want predictable response and reliable operation.

What this pinion brings to your setup

Swapping pinions is a simple way to change how your car pulls and tops out. This Serpent 120139 item is useful because:

Material: Quality aluminium construction reduces premature wear while keeping weight down.
Design: 64P, 52-tooth profile tuned for smooth engagement and lower noise.
Compatibility: Suits a broad selection of RC car motors and gearboxes for flexible tuning choices.

Will this gear change my car handling?

Changing the Serpent 120139 pinion alters acceleration and top speed; smaller tooth counts give more acceleration while larger counts raise top speed, so pick based on driving style.

Is shaft locking required for installation?

Most installations use a set screw or clamp style to secure the pinion. Ensure the shaft is clean and the fixing torque is correct to avoid slippage.

Can I use this on plastic spur gears?

Yes, but monitor wear. The aluminium pinion paired with a plastic spur can be fine for tuning, just check for wear patterns and adjust mesh to avoid premature damage.
