Performance Tuning for the Kyosho UB034 Ball Diff Screw & Spring Set

The Kyosho UB034 Ball Diff Screw & Tensioner Spring Set is intended for routine maintenance and setup tweaks that improve differential behaviour. Suited to drivers focused on dialling handling, the set helps maintain steady preload across the ball diff for reliable response.

Compatibility and Benefits

By pairing the correct screw with the tensioner spring, you can control diff preload and reduce unwanted slip or harsh engagement. This improves traction feel on surfaces ranging from club tracks to outdoor hardpack.

Practical Maintenance Advice

While the UB034 set is frequently fitted to the Ultima RB7.5, it also matches other Kyosho models with similar diff hardware. Regular inspection and replacement during service prevents drift in handling and keeps lap times consistent.
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.

Do I need specific grease with the UB034 set?

Use common diff grease suitable for ball differentials; avoid overly thin oils that can change preload feel. Grease choice will influence how the diff transfers torque.

Is fitting the UB034 set a workshop job?

Installation is straightforward with basic tools and some mechanical familiarity, but take care to set preload gradually and test on track to confirm settings.

Will these parts affect corner entry and exit?

Yes, adjusting diff tension changes how the car rotates through corners. Tighter preload can reduce inside wheel spin on corner exit, while looser settings can improve turn-in agility.
