18T 0.8Mod 1/8 Bore CNC Steel Pinion Gear (ARA311080)

This 18-tooth, 0.8-modulus CNC steel pinion gear is designed to fine-tune the gear ratio on 1/8-scale RC vehicles, letting you dial in the balance of speed and torque for demanding tracks and terrain.

Made from durable steel and precision CNC machined for accurate tooth engagement, it features a wide tooth profile for smooth operation and fits 1/8-inch (3.175 mm) motor shafts. The gear is laser-etched with the tooth count for quick identification and includes a threaded hole for an M4 x 4 mm set screw to secure it during operation.
