The idler and top shaft are made of steel, with excellent wear and impact resistance, suitable for high-intensity model competition environments.
The combination of idler and top shaft optimizes the power transmission path, reduces friction loss, and improves the overall operating efficiency and smoothness of the model car.
The steel structure is stable and durable, not easy to deform or damage, and can maintain good performance even under high load or frequent operation.
Contains 1 idler and 1 top shaft each. The set form is convenient for one-time replacement or upgrade, without additional purchase, and more user-friendly.
