Restore precise steering with Kyosho MZ8-3-1

The Kyosho MZ8-3-1 Servo Gear Shaft is a key spare for keeping your Mini-Z MR-03 running with accurate steering and consistent servo performance. Designed for the MR-03 RWD platform, this replacement shaft helps maintain smooth servo movement on track and during practice sessions.

Fitment and role

This gear shaft fits the Mini-Z MR-03 series and integrates cleanly with the original servo assembly. It is engineered to deliver steady, repeatable servo action so you can rely on crisp inputs and stable handling when racing or cruising.

Simple installation and upkeep

Installing the Kyosho MZ8-3-1 is straightforward for hobbyists familiar with Mini-Z servicing. Periodic inspection and light cleaning will prevent grit buildup and prolong shaft life. Check linkages and mounting points to keep the servo system operating at its best.
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 MZ8-3-1 work in other Mini-Z generations?

The MZ8-3-1 is made for the MR-03 series and is optimised for that layout. Other Mini-Z platforms may require different parts or adaptors.

How can I tell when the servo gear shaft needs replacing?

Look for slop in the steering, grinding noises, or inconsistent servo travel. Those signs usually mean the shaft or mating gears are worn and should be inspected.

Any tips for keeping the shaft long lived?

Keep the area free of dust and debris, avoid over-tightening linkages, and apply light lubrication only where recommended to prevent premature wear.
