Precision Swing Shafts for Ultima SB - Kyosho UM522B

The Kyosho UM522B Universal Swing Shaft is a direct-fit upgrade for Ultima SB models that need steadier power delivery. These shafts are produced to tighten drivetrain performance and extend service life during regular racing.

Balance of Strength and Smooth Operation

Created to tolerate the strains of competitive running, the universal swing shafts deliver reliable rotation across track surfaces. The 65.5mm specification matches the Ultima SB Dirt Master to preserve suspension geometry. Quality manufacturing helps prevent premature failure under repeated stress.

Main Advantages

  • Compatibility: Intended for the Ultima SB family
  • Durability: Longer lasting than stock swing shafts
  • Performance: Enhances drivetrain efficiency under load
  • Precision Fit: 65.5mm measurement keeps set-up true
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 these replace the original shafts directly?

They are made to fit the Ultima SB series and typically install in place of the standard swing shafts without major modification.

How do I check for correct alignment after fitting?

After installation, spin the wheels and inspect drive angles and suspension travel to ensure there is no binding or unusual noise.

Are these a maintenance upgrade or performance upgrade?

They serve both purposes by offering improved durability over worn parts and by refining drivetrain response for better control.
