Dial in ULTIMA traction with Kyosho UMW602B

For drivers focused on refining handling in the ULTIMA SC, DB, RB5 or RT5 range, the Kyosho UMW602B Ball Differential Set delivers steadier drive response and reduced wheel hop. It is suited to both club competition and faster backyard runs.

How a ball differential changes handling

Replacing a gear differential with a ball unit provides a smoother transition of torque between wheels and a more progressive slip feel. That balance improves mid corner stability and helps maintain forward drive on exit.

Compatibility details

The UMW602B has been crafted to fit ULTIMA SC, DB, RB5 and RT5 chassis layouts. Installation is normally direct, but confirm the housing and mounting hardware on custom or heavily upgraded cars.

Installation and care tips

Keep all parts free from grit during assembly and choose lubricant suited to your track conditions. Regular checks and light servicing will keep the unit performing consistently lap after lap.
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.

Does fitting this diff change gearing or top speed?

The differential itself does not change gear ratios or top speed, but it can affect traction and acceleration feel, which alters how the car delivers power on exit.

Can I adjust the preload on this unit?

Yes, preload and assembly adjustments allow you to fine tune how much resistance the diff provides, making it adaptable to different driving styles.

Are spare parts available for wear items?

Wear parts such as balls and plates can be replaced; check with parts suppliers for genuine Kyosho spares or compatible aftermarket components.
