Description
p
Extra-hard steel pinion gear for brushless RC cars, featuring a 5mm bore and 11 teeth. Made from high-carbon GEN3 steel for durability, it’s precision-machined and stamped with the tooth count to ensure a reliable mesh with the spur gear. A 4mm set screw is included, and tightening requires a 2mm Allen wrench (not included). Designed to fit a 5mm motor shaft, with a 5mm to 1/8″ reducer sleeve needed for 1/8″ shaft motors.
Compatibility and notes: This pinion can be used with 32 pitch and .8 module gears without adverse effects on wear or noise. The .8 module gears have a slightly larger outside diameter per tooth (about 0.00027 inches). Built for high-torque, long-lasting performance in demanding RC car setups.
