Overview
The ProTek R/C Steel Mod 1 Pinion Gear (15T, 5mm bore) is a precision-machined hardened steel pinion designed for high-power 1/8 scale and large-scale RC applications. With 15 teeth in Mod 1 pitch and a 5mm bore, it's the durable, race-ready gearing solution for big brushless motors that demand strength and reliability.
Hardened steel construction means this pinion stands up to the heat, torque, and abuse of high-power RC use far better than aluminum, making it a smart choice for serious bashers and racers alike.
