34T Mod1 Safe-D8 Pinion Gear (ARA311122)

The 34-tooth Mod 1 Safe-D8 pinion gear is a tough steel pinion designed for 8 mm motor shafts, built to deliver reliable power transfer in demanding RC applications.

A D-shaped drive hole matches the motor shaft to help keep the pinion engaged and prevent loss of drive if the set-screw backs out. The wide tooth profile promotes smooth mesh, and the steel construction offers long-lasting durability in extreme RC conditions. Sized for 8 mm shafts, it ships with a M4 x 4 mm set screw and a 6 mm E-clip to secure retention.
