When to Fit These Arms

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 special hardware needed to install these arms?

They typically fit with standard Ultima SB screws and pins. Replace any corroded fasteners during the swap for best results.

Will changing arms require suspension re-tuning?

Minor adjustments to camber or toe may be beneficial after installation, but major re-tuning is usually unnecessary if dimensions match stock parts.

Can these arms handle larger tyres and heavier setups?

They are robust enough for moderate tyre and weight increases, but extreme upgrades should be assessed for stress on mounting points.
