HRCSG1815 - 15t 48p Hardened Steel Pinion Gear 1/8 Bore

This product is a hardened steel 48 pitch pinion gear designed for 1/8 inch bore motor shafts, offering reliable and efficient power transfer in 1/10 scale RC vehicles. The 15-tooth configuration increases torque and acceleration while slightly reducing top speed, making it ideal for technical driving and heavier setups. Precision-cut teeth ensure smooth gear mesh with minimal noise and reduced wear on spur gears. Constructed from heat-treated 4140 steel, it provides long-lasting durability under high torque and brushless power systems. Its compact design maintains proper alignment and consistent drivetrain performance.
