15T Mod1 Safe-D5 Pinion Gear (ARA310962)
The 15T Mod1 Safe-D Pinion Gear is a tough steel pinion designed for 5mm motor shafts in RC cars and trucks. This compact 15-tooth gear translates motor power into drivetrain motion, with a Safe-D design that uses a D-shaped bore to keep the drive engaged even if the set-screw backs out.
Built for durability in demanding RC conditions, it features a precision wide tooth profile for smooth meshing with the spur gear and is sized for 5mm shafts with a threaded set-screw hole for secure mounting. The package includes one 15T Mod1 Safe-D Pinion Gear, one M4 x 4mm set screw, and one 3.2mm E-clip to retain the pinion on the shaft.
