For hobbyists aiming to tune gear engagement, the Tamiya 54218 RC TRF201 48 Pitch Pinion Gear Set provides two pinions - a 24T and a 25T - built to lower operating noise and reduce friction during use.
The tooth geometry helps ensure cleaner contact between pinion and spur, reducing friction and helping the drivetrain run with less vibration and audible noise.
Each pinion includes two grub screw holes so you can choose the best set screw placement for your motor shaft and chassis, improving alignment and securing the gear under load.
