30T 0.8Mod 1/8 Bore CNC Steel Pinion Gear (ARA311092)

Designed to fine-tune the gear ratio on 1/8-scale RC vehicles, this 30-tooth, 0.8 module CNC steel pinion gear is built for precision and durability. Machined from hardened steel for long-lasting performance, it features a wide tooth profile for smooth engagement and is laser-etched with the tooth count for quick identification. It is sized to fit 1/8-inch (3.175 mm) motor shafts.

It includes a threaded hole for a secure set screw, and a matching M4 x 4 mm set screw is supplied to lock the gear to the shaft, providing a precise, wobble-free fit. This rugged CNC pinion helps optimize drivetrain feel and response when paired with compatible spur gears in the right gearing setup.
