27T 0.8Mod 1/8 Bore CNC Steel Pinion Gear (ARA311089)

Designed to fine-tune the gearing of 1/8-scale RC vehicles, this 27-tooth, 0.8-module CNC steel pinion gear features a 1/8-inch bore to fit standard motor shafts. It helps dial in acceleration and top speed by adjusting your gear ratio, giving precise control over how your vehicle performs on the track or in the field.

Forged from durable steel and CNC-machined for accuracy, it offers a wide tooth profile for smooth engagement under load. The tooth count is laser-etched for quick identification, and a threaded hole accepts an M4 x 4 mm set screw, which is included to secure the gear onto the shaft during use. This pinion is designed for reliable, long-lasting performance in demanding RC environments.
