31T Mod1 Safe-D8 Pinion Gear (ARA311119)

This 31T Mod1 Safe-D8 pinion gear is a rugged steel component designed for RC models, delivering reliable power transfer on 8mm motor shafts with 31 teeth for steady, predictable performance under load.

Constructed from durable steel with a wide tooth profile for smooth engagement, it features a D-shaped hole that mates with the motor shaft to prevent loss of drive if the set-screw backs out. It uses a threaded hole for the set screw and comes with an M4 x 4mm set screw and a 6mm E-clip to secure the pinion on the shaft.
