The Kyosho W0137B 6.8 Hard Ball set supplies ten M3.0 ball connectors that help maintain smooth movement in RC models. It is a practical spare parts pack for builders and racers who like to keep things tight and predictable.
These hard balls are suited to suspension and steering linkages where a secure connection matters. Their solid build reduces play and supports consistent behaviour through repeated sessions.
Designed with 1/10 scale layouts in mind, the Kyosho W0137B hard balls work with many kits that accept M3.0 components. They are a sensible option for people who often change setups to suit different surfaces.
