Upgrade RB7 Clutch Control with Kyosho UM774

The Kyosho UM774 Slipper Spring Set is a targeted upgrade for the RB7, built to deliver smoother clutch engagement and improved driveability. These springs help stabilise the slipper action so you get repeatable behaviour lap after lap in club and regional racing.

Clutch Modulation for Track Conditions

Engineered for fine control, the UM774 springs let you dial in power transfer to reduce wheel spin and boost traction across asphalt and carpet tracks. Better modulation helps when exiting tight corners and when applying throttle on variable grip surfaces.

Fitting Advice for Reliable Service

Fit the Kyosho UM774 set with careful alignment of the slipper plates and keep fasteners torqued to spec. Inspect the assembly regularly for wear and follow the RB7 service manual for step by step guidance to maintain consistent performance.

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 UM774 springs work in other Kyosho kits?

These springs are made for the RB7 slipper layout. They may fit other Kyosho models with similar slipper assemblies, but you should compare dimensions and mounting before swapping them in.

How do I know when to replace the slipper springs?

Check for loss of spring tension, uneven engagement or excessive play. Replace the springs if you notice inconsistent clutch behaviour or visible fatigue to keep lap times consistent.
