36T Mod1 Safe-D5 Pinion Gear (ARA311131)

This 36-tooth Mod1 Safe-D5 pinion gear is a tough steel gear designed for high-performance RC powertrains. It meshes with the spur gear to transfer motor torque to the drivetrain, and its precision-tooth profile promotes smooth, reliable operation and lasting durability in demanding RC conditions.

It fits a 5mm motor shaft and comes with an M4 x 4 mm set screw and a 3.2 mm E-clip for secure retention. The D-shaped bore matches the shaft profile to keep the pinion engaged even if the set screw backs out, while the precisely threaded set-screw hole and sturdy construction support consistent, dependable performance.
