Smoother Power Delivery for RB5 SP

The Kyosho UM522 swing shaft at 65.5mm is built to tighten driveline action on RB5 SP machines. It reduces lash in the transmission path so throttle response feels more immediate and predictable on mixed surfaces.
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 reuse my existing hardware with the UM522?

In many cases your current pins and grub screws will work, but always check fitment and replace any worn fasteners to ensure a secure installation.

Does the length affect handling?

The 65.5mm length matches RB5 SP layout and helps maintain correct geometry. Using the specified length preserves intended suspension and driveline angles.

Should I check other parts when fitting this shaft?

Yes. Inspect cups, bearings and diff outdrives for wear and replace any degraded parts to keep the new shaft performing well.

Is any special grease recommended?

Use a light to medium grease on splines for smooth engagement, and avoid heavy pastes that can attract grit in dusty conditions.
