32T Mod1 Safe-D5 Pinion Gear (ARA311137)

The 32-Tooth Mod1 Safe-D5 Pinion Gear is designed for RC models and built from tough steel to withstand demanding RC conditions. This gear makes a reliable addition to any toolkit, and it includes the hardware needed for quick installation: an M4 x 4 mm set screw and a 3.2 mm E-clip.

It features a wide tooth profile for smooth, reliable engagement with the spur gear. The D-shaped hole matches the motor shaft profile to help keep the pinion securely seated if the set-screw backs out. It fits 5 mm motor shafts and includes a precisely threaded set-screw hole and an E-clip for secure retention.
