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.

Which RC models will accept these 4.8mm ball studs?

These studs are sized for many hobby-grade touring cars, buggies and short-course trucks that use 4.8mm link hardware. Check your model's parts list or measure your existing ball stud to confirm fit.

Do I need special tools to fit the UM129B studs?

No special tooling is required beyond basic hobby tools. A small spanner or pliers and a suitable thread locker for metal threads will make installation quick and secure.

How should I maintain these ball studs for longevity?

Keep the studs clean of dirt and inspect for wear after heavy sessions. Light lubrication and periodic replacement when play appears will preserve steering precision.
