Tamiya 22021 - GB-01S Aluminum Pinion Gear 16T Upgrade  [22021]

Solid Upgrade for TamTech-Gear Drive

Benefits of a Hard Coated Aluminum Pinion

Hard coating on aluminum helps reduce surface wear compared with standard gears, giving longer life under heavy use. That improved durability is useful for frequent track sessions or rough off-road running, while the light weight of aluminum keeps rotational mass low for steady acceleration.
