Tune Your Mini-Z MR-03 with Kyosho MZW407

The Kyosho MZW407 stainless king pin ball is a straightforward performance upgrade for the Mini-Z MR-03 line. Made to last, this part improves the vertical motion of the knuckle to reduce play and sharpen on-track handling.

Built for Reliable Handling

Machined from corrosion-resistant stainless steel, the king pin ball resists wear while its smooth surface cuts friction. That translates to steadier steering inputs and crisper response during quick direction changes.

Fit Notes and Installation

Designed specifically for Kyosho Mini-Z MR-03 chassis, the MZW407 installs easily with standard Mini-Z tools and fits the stock knuckle assembly. It is ideal for routine maintenance or modest performance upgrades.
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.

Will the MZW407 work on older MR-03 variants?

The MZW407 is made for MR-03 geometry; it should fit most MR-03 versions but check your knuckle dimensions before fitting to be sure.

Do I need special grease for this part?

Use a light metal-safe lubricant on moving interfaces. Heavy greases can attract dirt and reduce the intended low-friction benefit.

How often should I inspect the king pin ball?

Inspect during regular maintenance intervals or after impacts. Check for play or surface wear and replace if any binding or looseness appears.
