Fine Tune Clutch Behavior on the RB7.5 with Kyosho UB038

The Kyosho UB038 slipper spring set is engineered for the Ultima RB7.5 chassis to give hobbyists and club racers tighter control over slipper action. These springs help stabilise power transfer and reduce inconsistent slips during demanding sessions.

Core Benefits of the Kyosho UB038 Slipper Springs

  • Compatibility: Specifically matched to the Ultima RB7.5 for a correct fit and reliable operation.
  • Performance: Improves repeatable clutch engagement, useful when fine tuning acceleration and corner exits.
  • Durability: Made to resist frequent race stresses so you spend more time running and less time replacing parts.
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 UB038 work with my older RB7 variants

These springs are designed around the RB7.5 geometry. Older RB7 versions may require checking hub spacing and slipper plate clearance before attempting installation.

What setup changes should I make after fitting UB038

After fitting UB038, retune your slipper nut and test on your regular track surface to find the balance between grip and slip for consistent launches.

Are there recommended maintenance steps for these springs

Inspect springs for fatigue after heavy events, keep the slipper area clean of debris and check slipper pad condition to ensure stable performance.
