Differential Case for B-MAX4 III Chassis

This RC-scale gear differential case fits the B-MAX4 III platform and is offered as a replacement housing to contain gear-type differential systems. The copy highlights fitment, access for tuning, and service considerations without asserting extra technical data.

Use this case when servicing the differential on a B-MAX4 III, replacing damaged housings, or when checking internal gears and bearings. It secures the differential gears and preserves the alignment and mesh that influence throttle response and cornering balance.

Installation is user-friendly for those experienced with differential rebuilds: remove the assembly, transfer gears and spacers into the new case, and reassemble while verifying backlash and smooth rotation. While the housing does not modify differential behavior, it provides steady reassembly and dependable access for tuning and lubrication tasks.
Remark :
Due to limited stock availability, please notice that some Yokomo 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 changing the case affect tuning outcomes?

The case itself does not change differential characteristics, but a correct replacement helps maintain consistent mesh and rebuilds, which supports predictable tuning results.

Are there any assembly tips to improve drivetrain smoothness?

Ensure bearings are seated, use correct spacers, set a light but even gear mesh, and rotate the assembly by hand before final sealing to confirm smooth operation.

Is lubrication required right away after fitting?

Apply appropriate gear grease or oil to the internal gears and recheck free movement; fresh lubrication helps prevent premature wear and improves initial break-in behavior.
