Extra Hard Steel 5mm Bore 1mod pinion 12T (RRP1212)

Extra-hard steel pinion gear with a 5mm bore, 1.0 module, and twelve teeth, built for brushless RC car setups. It is designed to mesh with spur gears used on most 1/8-scale nitro configurations, providing a reliable link between the motor and drivetrain.

One 4x4mm set screw is included to secure the pinion on a 5mm motor shaft, and a 2mm Allen wrench is required to tighten it (not included). It is compatible with most 1/8-scale nitro spur gears, and for motors with a 1/8-inch shaft, a 5mm-to-1/8-inch reducer sleeve is required. The pinion is manufactured from extra-hard steel for durability during high-power driving.
