Restore Steering Precision with Kyosho MZ404B for Mini-Z MR-03

The Kyosho MZ404B is supplied as a replacement servo gear set for Mini-Z MR-03 RWD cars, aimed at restoring exact steering response and smooth servo movement. Fitting the correct gears helps retain predictable handling under varying conditions.

Fitment and Where to Use

Recommended for MR-03 RWD variants, this set assists hobbyists who need to swap out worn components to keep lap times consistent. The MZ404B is intended to match the original layout so the steering geometry remains unchanged.

Practical Installation Hints

Prior to installation, clear out any dust and old lubricant from the servo cavity to avoid abrasion. Fit the gears with care, set the mesh just right, and confirm the servo centers before returning the car to full use. Regular maintenance checks will extend the service life of the system.
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 the Kyosho MZ404B compatible with all MR-03 variants?

The set is intended for MR-03 RWD models. Other MR-03 versions may use different servo layouts, so verify the part fit before purchase.

How often should I inspect the servo gears?

Inspect gears whenever you notice steering play or after heavy use. A quick check every few outings will help catch wear before it affects handling.

What maintenance keeps gears lasting longer?

Keep the servo area clean, avoid over greasing the mesh, and ensure correct gear mesh and secure fastenings. These steps reduce wear and improve reliability.
