Tune Your R4 Evo.3 with Kyosho VZ509 Hard Balls

Kyosho VZ509 hard balls at 6.8mm are made to improve the responsiveness and durability of R4 Evo.3 steering and suspension linkages. The 2.5mm hex interface ensures a tight, repeatable fit, making them a practical choice for racers focused on consistent lap times.

Strength That Keeps Handling Consistent

Finished from robust materials, these hard balls stand up to regular racing loads to reduce play and maintain suspension geometry. Their construction supports a firm, predictable feel that helps drivers fine tune cornering and steering inputs.

Simple Fitment to R4 Evo.3 Chassis

The VZ509 units are manufactured to match R4 Evo.3 dimensions for direct replacement or upgrade. Install them to replace worn parts or to tighten up the front end without modifying existing components.
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.

Will Kyosho VZ509 fit other Kyosho models?

They are made for the R4 Evo.3 geometry but may fit other models with similar linkage dimensions. Always compare the 6.8mm size and mounting geometry before fitting into a different chassis.

What tool do I need to install these hard balls?

A 2.5mm hex driver is required to secure the hard balls. Use a quality hex driver to avoid stripping and to achieve correct preload.

How do I tell when to replace the hard balls?

Check for visible wear, looseness at link points, or increased steering slop. If you notice play or inconsistent steering feel, replace the worn units to regain precise handling.
