Track Tuned Slipper Spring for RB7.5 by Kyosho

The Kyosho UB038 slipper spring set is a purpose-built upgrade for the Ultima RB7.5 chassis. This set helps you fine tune clutch engagement for sharper starts and more predictable power delivery during competitive races, while improving wear resistance compared to stock springs.

Why Choose the Kyosho UB038 Slipper Springs

  • Compatibility: Made specifically for the Ultima RB7.5 so installation is straightforward and fitment is reliable.
  • Performance: Refines clutch bite and repeatability to help drivers get consistent lap times.
  • Durability: Manufactured to endure race conditions and reduce the need for frequent spring changes.
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 the UB038 springs to other Kyosho models

The UB038 springs are tailored for the Ultima RB7.5. They may fit other models only with adapter parts or modifications, so check measurements before trying to install them.

How will these springs change clutch feel on race day

Expect crisper engagement and more consistent slip characteristics, which helps when dialing in launch and throttle control on varying track surfaces.

Do I need to change other parts when upgrading to UB038

You may want to check slipper plates and pads for wear and set the slipper tension to match the new springs for best results, but no mandatory parts swap is required.
