Fit and Function for the Ultima RB7.5 with Kyosho UB001

The Kyosho UB001 Aluminium Crank Arm is built to refine the handling of the Ultima RB7.5. Using durable aluminium, the part gives tighter steering feedback and stands up to regular track abuse.

Stiffness Without Excess Weight

Kyosho sourced quality aluminium for the UB001 to increase component life while keeping weight down. The accurate machining keeps tolerances tight so the steering linkage operates smoothly during hard driving.

Straightforward Installation on RB7.5

Made to match the Ultima RB7.5 layout, this crank arm slips into place with minimal fuss. It is suited for racers replacing worn arms or those wanting a step up in reliability and control.
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.

Is this usable on older Ultima cars?

It is optimised for the RB7.5 geometry, so older Ultima models may require measurement and modification to fit correctly.

Do I need special fasteners?

Standard hardware from the RB7.5 can usually be reused, but inspect screws and replace any that show wear. Use light thread locker where appropriate.

How does this affect handling?

Expect crisper steering input and less flex under load, which helps maintain consistent lines lap after lap.

Any maintenance advice?

Regularly check for burrs or damage and clean contact areas. Replace if significant wear appears to keep steering precise.
