Precision Slipper Springs for RB7 - Kyosho UM774

The Kyosho UM774 Slipper Spring Set is designed to upgrade the RB7 slipper for more reliable clutch feel. These springs provide consistent preload and predictable engagement to help you hit tighter lines and smoother throttle transitions on race day.

Better Traction Through Tuned Engagement

With improved spring characteristics, the UM774 set reduces sudden wheel spin and helps transfer power more smoothly to the tyres. That improved traction is useful on mixed surfaces and when trimming the car for quicker corner exits.

Simple Setup and Routine Care

For best results, install the Kyosho UM774 springs following the RB7 assembly notes and verify alignment of the slipper pads. Regular inspections and light maintenance will extend their service life and sustain consistent clutch behaviour.
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 fit these springs to an aftermarket slipper assembly?

They are matched to Kyosho RB7 geometry, so fitting to third party assemblies depends on shaft diameter and plate spacing. Measure the assembly and compare before attempting a swap.

What track surfaces suit the UM774 springs?

These springs work well on high and medium grip surfaces like carpet and asphalt, giving smoother power delivery where traction varies through a lap.

Any quick setup tips for RB7 users?

Start with the stock slipper clearance, fit the springs, then test with small throttle inputs. Adjust slipper nut preload slowly until you find a balance between bite and slip for your conditions.
