Improve MR-03 Steering with Kyosho MZW407

The Kyosho MZW407 stainless king pin ball is a compact upgrade for the Mini-Z MR-03 chassis that smooths knuckle motion and reduces lateral play. It is suitable for maintenance and light tuning tasks.

Low Friction Design

Crafted from stainless steel with a fine finish, this king pin ball minimises friction at the knuckle joint and maintains consistent steering feel. The harder material also extends service intervals.

Fitment and Use

Made to match Kyosho Mini-Z MR-03 dimensions, the MZW407 installs into the stock knuckle without modification. Check alignment during refit and use light lubrication on contact points for best results.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is installation beginner friendly?

Basic Mini-Z experience and standard tools are enough to replace the king pin ball. Follow step-by-step guides if you are new to knuckle service.

How does stainless compare to brass or plastic?

Stainless offers better wear resistance and lower long-term deformation than softer materials, making it a sensible choice for frequent drivers.

Any tips to prolong service life?

Keep the area free of grit, use small amounts of appropriate lubricant, and inspect the ball for signs of scoring after impacts to ensure long life.
