KYOMZW417 Metal Servo Gear(4th)for MR-03

Built for Kyosho Mini-Z MR-03 chassis platforms, this metal servo gear (4th gear) is designed to reinforce the steering servo assembly for improved durability and long-term reliability. Manufactured from brass material, it replaces the stock plastic 4th gear to better withstand wear from repeated steering inputs and high-load driving conditions. It is intended as a direct upgrade part within the MR-03 steering gearbox, helping maintain smooth and consistent steering response while reducing the risk of gear stripping. The precision-cut design ensures proper mesh with the remaining servo gear train for stable operation.

Features:

• Designed for Kyosho Mini-Z MR-03 chassis compatibility
• Brass metal construction for increased durability
• Reinforces 4th stage servo gear in steering assembly
• Reduces wear and risk of gear stripping
• Improves long-term steering reliability
• Precision-fit gear mesh for smooth operation
• Direct replacement upgrade for stock plastic gear
