Extra Hard 20 Tooth Blackened Steel 32p Pinion 5mm (RRP8620)

Extra-hard 20-tooth pinion for 5mm motor shafts. This 32-pitch, high-carbon gear is built to last and ideal for use with metal spur gears in demanding RC setups.

Made from high-carbon steel and heat-treated to boost surface hardness, it offers durable performance with smooth operation. Each pinion is precision-machined and stamped with the tooth count, and includes a 4mm set screw for secure installation (a 2mm Allen wrench is not included). It fits 5mm shaft motors and is compatible with popular brands such as Traxxas, Associated, and HPI. The combination of 32-pitch and 0.8 module gears is supported, and they can be used together without noticeable increases in noise or wear; for motors with 1/8-inch shafts, a reducer sleeve may be required.
