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.

Can I use this differential with standard Ultima gearing?

Yes, the UMW604B is compatible with standard Ultima gear ratios and installs into the original differential location.

Does it require special oils or greases?

The unit benefits from light differential grease on bearings and correct gear lubrication; follow standard RC diff service practices for best results.

Will this change my car's balance?

It can shift traction characteristics towards more consistent rear-end behaviour, so small suspension or toe adjustments may be helpful after installation.

How easy is installation for a hobbyist?

Installation is straightforward for those comfortable with basic teardown of the rear diff assembly; use proper tools and keep fasteners torqued to spec.
