Apex RC Products 11T & 12T Mod 1 Pinion Gear Set (2-Pack) for 1/8 Scale RC Cars

This Apex RC Products pinion gear set includes two CNC-machined steel gears: one with 11 teeth and one with 12 teeth. Both gears are Mod 1 pitch (M1), have a 5mm bore, and are designed for 1/8 scale RC vehicles. Each gear is engraved with its tooth count for quick identification. The steel construction is built to offer strong durability during use.

Pinion Gear Sizes and Fit

This set provides two of the most common starting tooth counts for 1/8 scale RC cars: 11 teeth and 12 teeth. Both gears use the Mod 1 (M1) module, which is standard for many 1/8 scale drivetrains. The 5mm bore fits many common motor shafts. Always double-check your motor shaft diameter and the gear pitch required by your vehicle's transmission before installation.
