Extra Hard Steel Pinion Gear 5mm Bore Mod1.0 11T (RRP1211)

This extra-hard steel pinion gear features a 5mm bore and 11 teeth, a 1.0 module size, and is designed for RC cars with brushless motors. It works with most 1/8-scale nitro spur gears to fine-tune speed and torque, and includes a 4x4mm set screw for mounting on a 5mm motor shaft.

Made from hardened steel for durability, this pinion is intended for 5mm motor shafts. A 2mm Allen wrench (not included) is required to tighten the set screw. For motors with 1/8-inch shafts, a 5mm to 1/8-inch reducer sleeve is required to adapt.
