Fine Tune RB7 Slipper Action with Kyosho UM774

The Kyosho UM774 Slipper Spring Set is a focused upgrade that improves the slipper mechanism on the RB7, delivering more consistent engagement and easier tuning. These springs help maintain steady clutch behaviour for repeatable performance on race day.

Controlled Engagement for Improved Handling

With the UM774 springs fitted, power is fed to the wheels in a more controlled manner, reducing sudden loss of traction and improving stability on corner exits. They are particularly useful when dialling in the car for close competition.

Practical Fitment and Maintenance Tips

Install the Kyosho UM774 set following the RB7 assembly guidance and check that the slipper plates sit flush. Regular maintenance and timely replacement of fatigued springs will keep the slipper functioning reliably.

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 these springs change my slipper feel a lot?

They offer firmer, more predictable engagement compared to worn or softer springs, but how noticeable the change is depends on your current setup and driving style.

Do I need special tools to fit the UM774 springs?

No special tools are required beyond standard RC workshop gear. Careful alignment and correct torque settings are the main concerns during fitting.
