Overview
The Robinson Racing 25-Tooth Extra Hard Steel Pinion Gear is engineered for high-performance 1/10 scale RC applications. With a 5mm bore and 0.8 module pitch, this pinion is built to withstand the demands of powerful brushless motor systems including Traxxas, Associated, and HPI platforms.
Made from high carbon steel and heat-treated for maximum hardness, this pinion gear naturally runs cooler and quieter than softer grades of steel. The precision machining ensures perfect gear mesh with your spur gear for efficient power transfer.
