Extra Hard Steel Pinion Gear 5mm Bore Mod0.8 14T (RRP8714)

Extra-hard high-carbon steel pinion gear built for brushless RC car setups, delivering durable, long-lasting performance. This 5mm-bore, 0.8-module pinion has 14 teeth and is precision‑machined for consistent mesh with the matching spur gear. A 4mm set screw is included to secure it to a 5mm motor shaft, and a reducer sleeve is required for motors with a 1/8-inch shaft.

Designed for high-torque brushless power, it works with standard gear trains that use 32-pitch gearing. The 0.8-module design carries a slightly larger diameter per tooth than some alternatives, but the difference is small and does not typically result in increased noise or wear in normal use.
