Upgrade ULTIMA handling with Kyosho UMW602B

For RC enthusiasts wanting sharper control on their ULTIMA SC, DB, RB5, or RT5, the Kyosho UMW602B Ball Differential Set is a sensible upgrade. It is made to reduce wheel hop and deliver smoother traction for demanding tracks and spirited club runs.

Advantages of the ball differential

This ball differential replaces stock gear units to give more progressive power split between drive wheels. The result is improved cornering balance and less tyre spin when exiting bends, which helps drivers who push higher corner speeds.

Model fit and fitment notes

The UMW602B is engineered specifically to fit ULTIMA SC, DB, RB5 and RT5 chassis without major modification. Its dimensions and mounting points match the originals for a straightforward swap.

Basic fitting and upkeep

When fitting the Kyosho UMW602B Ball Differential Set keep parts clean and avoid contaminating bearings with grit. Regular inspection and the correct grease or oil will preserve smooth operation and extend service life.
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.

Will the UMW602B work in older ULTIMA variants?

This kit is made for the ULTIMA SC, DB, RB5 and RT5 platforms; confirm your chassis layout and differential carrier before fitting to older or heavily modified cars.

What maintenance does a ball differential need?

Clean the unit regularly, check for wear on balls and plates, and use the recommended lubricant to keep engagement consistent and reduce noise.

Do I need special tools to install it?

Basic RC tools suffice: hex drivers, a small screwdriver and a torque-friendly driver for hub nuts. A clean workspace and patience will make the install straightforward.
