HRCSG1820 - 20t 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, providing efficient and reliable power transfer in 1/10 scale RC vehicles. The 20-tooth configuration increases top speed while slightly reducing low-end torque, making it well suited for high-speed setups and smoother track conditions. Precision-cut gear teeth ensure consistent mesh with spur gears, reducing noise and premature wear. Constructed from heat-treated 4140 steel, it offers excellent durability under high torque and brushless systems. Its compact and balanced design helps maintain proper gear alignment for consistent drivetrain performance.
