25T 0.8Mod 1/8 Bore CNC Steel Pinion Gear (ARA311087)

A 25-tooth, 0.8 module CNC steel pinion gear designed for tuning the gear ratio on 1/8-scale RC vehicles. It features a 1/8 inch bore to fit standard motor shafts and is CNC-machined for precise alignment and long-lasting durability.

Constructed from tough steel, it uses a wide tooth profile for smooth operation and reliable power transfer under demanding driving. The tooth count is laser-etched for quick identification, and a threaded hole accepts an M4 x 4mm set screw to secure the gear on the shaft. It fits 1/8 inch (3.175 mm) motor shafts and includes the set screw to complete the installation.
