Refined Drivetrain Component for RB5 SP

The Kyosho UM522 universal swing shaft at 65.5mm is made to tighten up the transmission path on RB5 SP cars. By reducing slack and improving spline engagement, it helps deliver more consistent torque to the wheels during demanding runs.
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 the UM522 a direct swap for the stock shaft?

For RB5 SP fitments it is a direct replacement in length and mounting. Confirm your current setup matches RB5 SP specifications before fitting to other variants.

Will this part reduce drivetrain noise?

By improving spline engagement and reducing play, the UM522 can help lower clunking and lash, leading to a quieter driveline when installed correctly.

Are upgrades needed alongside this shaft?

Upgrading worn bearings, cups or diff components is recommended to get the best results. A healthy surrounding driveline maximises the benefit of the new shaft.
