Built for Kyosho’s Mini-Z MR-04 platform, this ball differential set is designed to replace the standard gear diff and deliver smoother, more controlled power transfer through corners. The ball-type mechanism reduces inside wheel unload during turning, helping maintain consistent traction and more stable acceleration out of bends. It is engineered as a direct-fit upgrade for MR-04 chassis setups, offering improved tuning capability for competitive racing. The lightweight construction also helps keep drivetrain response sharp and efficient.
