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 stack multiple UM523 spacers for extra offset?

Stacking spacers can increase offset but may require longer fasteners and a check of clearance to surrounding components. Make incremental changes and test handling between adjustments.

Will the spacer change motor heat transfer or cooling?

The spacer moves the motor slightly but does not significantly affect cooling. Ensure your motor has adequate airflow and monitor temperatures after any setup change.

Is the UM523 suitable for both on-road and off-road tuning?

Yes, the spacer can be used on both on-road and off-road RB5, RT5 and SC variants to refine weight distribution and handling characteristics specific to each surface.

Do I need new motor mount screws when fitting the spacer?

Often the original screws are fine, but longer screws may be needed if you use thicker spacers or stack them. Check thread engagement and torque settings after installation.
