Aluminum Pro Pinion Gear 1/8" Bore 64P 39T (RRP4339)

Pro Aluminum Pinion Gear, 64-pitch with 39 teeth and a 1/8-inch bore, is a precision-built component for RC transmissions. It is precision-machined from aircraft-grade aluminum, lightened, and double-coated with a hard black anodize for durability. While recommended for on-road use, it can also be used off-road.

The tooth count is stamped on each pinion for easy identification, and one 5-40 set screw is included for secure mounting. A 1/16-inch Allen wrench is required to tighten the set screw and is not included. This pinion is designed to fit 1/8-inch bore configurations, delivering reliable performance in everyday RC hobby applications.
