Arrma ARA2032 Pinion Gear 19T 0.5 MOD CNC 3.2mm Bore

The Arrma ARA2032 is a 19-tooth, 0.5 MOD CNC-machined pinion gear designed for small-scale Arrma RC vehicles running a 3.2mm motor shaft. Pinion gears are a common wear item and a direct replacement like the ARA2032 keeps your drivetrain running at the correct gear ratio without the need for modification. The 0.5 MOD pitch and 3.2mm bore are specific measurements, so confirming your motor shaft diameter and existing spur gear MOD before ordering is essential.

Key Features

• CNC machined construction for consistent tooth profile and accurate fitment on the motor shaft
• 19-tooth count suits standard gear ratio configurations in compatible Arrma models
• 0.5 MOD pitch must be matched to a 0.5 MOD spur gear for correct mesh and drivetrain efficiency
• 3.2mm bore diameter is sized for small-scale brushed or brushless motors with a 3.2mm shaft
• Direct OEM replacement part — no modification required for supported models
