Description
Pro Aluminum Pinion Gear, 21 teeth, 48-pitch with a 1/8-inch bore, designed to drive the spur gear in a model vehicle transmission.
Machined from aircraft-grade aluminum and lightened for performance, it is coated twice with a hard black anodize for durability. The tooth count is stamped on the gear for quick identification, and a 5-40 set screw is included for secure mounting. While recommended for on-road use, it can handle off-road conditions as well.
