ARRMA 13T 0.5 MOD CNC 2.3mm Bore RC Pinion Gear - ARA-2628

The ARRMA ARA-2628 is a 13-tooth, 0.5 MOD CNC-machined pinion gear with a 2.3mm bore, designed as a drivetrain component for compatible ARRMA electric RC models. Pinion gears are a critical part of the RC drivetrain, sitting on the motor shaft and meshing with the spur gear to transfer power to the wheels. The ARA-2628 is precision-machined rather than stamped or moulded, which helps maintain consistent gear mesh and dimensional accuracy during fitment.

Key Features

• 13-tooth, 0.5 MOD specification for correct mesh with compatible 0.5 MOD spur gears
• CNC-machined construction ensures precise tooth profile and bore dimensions
• 2.3mm bore diameter fits the motor shaft of compatible ARRMA electric models
