Refine ULTIMA cornering with Kyosho UMW602B

RC builders aiming to tighten handling on ULTIMA SC, DB, RB5 or RT5 models will find the Kyosho UMW602B Ball Differential Set a useful upgrade. It improves wheel cooperation and helps the car track cleaner through technical sections.

Performance benefits explained

Compared with standard gear differentials, a ball differential offers adjustable slip characteristics and smoother transfer of drive torque. That makes it easier to modulate traction on loose or mixed surfaces.

Where this kit fits

This ball differential is built to match the ULTIMA SC, DB, RB5 and RT5 mounting points, meaning it installs without major chassis changes. Check exact model variants to ensure full compatibility.

Setup pointers and service

Clean parts and use proper differential grease or oil when assembling. Periodic teardown to inspect balls and plates will keep the UMW602B operating predictably during club meets and weekend runs.
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.

Can I tune the diff for grip or oversteer?

Yes, by adjusting preload and using different lubricants you can bias the diff toward more locking for traction or freer action for easier rotation during corner entry.

Is this suitable for dirt tracks as well as carpet?

The ball differential performs well on varied surfaces; use heavier diff oil for loose dirt and lighter oil for carpet or smooth tarmac to tune slip behaviour.

How often should I service the diff?

Service intervals depend on use, but inspect after every few running sessions or sooner if performance degrades or contamination is suspected.

Will bearings from the original diff work with this kit?

Many original bearings are compatible, but verify sizes before reuse; worn bearings should be replaced to avoid premature wear on the ball surfaces.
