Tune Your Drive with the Serpent 120159 Pinion

The Serpent 120159 - 48P 21T Aluminum Motor Pinion Gear is produced from high-grade aluminium to offer a sturdy pinion choice for your RC. The 48-pitch, 21-tooth geometry promotes true meshing and steady torque delivery, suitable for both competition setups and backyard running.

Strength and Low Weight

This aluminium pinion balances toughness with lower mass to reduce rotational load on the motor. The Serpent 120159 construction helps improve throttle response and can ease battery drain over hard runs, while standing up to regular track use.

Compatibility and Setup Advice

Fits systems that use 48-pitch gears; the 21-tooth size provides a useful compromise for speed versus torque. Always match the pinion to the motor shaft diameter and fine-tune mesh to avoid tooth chipping and noisy operation.

Can I use this on my brushless setup?

Yes, it works with brushless or brushed motors as long as the shaft size and 48-pitch gearbox are compatible.

Will aluminium wear quickly under high power?

Aluminium can show wear faster than hardened steel in extreme use, but high-quality aluminium pinions like this one hold up well for typical racing and hobby use when meshed correctly.

Should I change gear ratios when switching pinions?

Yes, swapping tooth counts affects final drive. A 21-tooth pinion will alter top speed and acceleration, so re-evaluate gearing to match track or terrain demands.

How do I check pinion mesh correctly?

Place a thin shim or a strip of paper between pinion and spur, bring gears together, tighten, then remove the shim and rotate the gears to confirm smooth engagement with minimal play.
