Precision Linkage Upgrade for the R4 Evo.3

The Kyosho VZ509 6.8mm hard balls are intended to tighten up critical link points on the R4 Evo.3 chassis. Their 2.5mm hex fitting provides a reliable interface for consistent alignment and predictable steering behaviour.

Robust Construction for Track Use

Built from quality materials, these hard balls resist degradation from frequent running and help maintain suspension geometry. That durability supports more consistent lap times and fewer part changes between meetings.

Direct Fit Replacement or Upgrade

VZ509 hard balls match R4 Evo.3 dimensions for straightforward replacement or upgrade. They are a practical option when refreshing worn link hardware or when you want a firmer front end response.
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.

Are these suitable for beginner tuners?

Yes, they are simple to fit and can make setup feel more precise. Beginners will notice reduced play, but should inspect fitment and alignment after installation.

Will the VZ509 affect durability of related parts?

The harder pivot points may transfer load to adjacent components if those are already worn. When upgrading, check link rods and ball cups for wear to ensure balanced durability.

Can I run these on different track surfaces?

They are best suited to smooth race surfaces where precise steering matters. On rough or loose surfaces you should inspect them more often for impact damage.

What should I check after installing the hard balls?

Verify the 2.5mm hex fasteners are torqued correctly, confirm there is no undue binding in the suspension, and perform a short test run to check steering alignment and feel.
