Have to agree with both the Durga I had and my current 501x I have never had a ball cup pop off and it's not like I haven't give them chance!

I've had a ball cup pop off at practice but never at a race.
But it would be good to put something stronger on the car anyways.
Wish I could find some schumacher ball cups, those things are strong.
A local guy had them on his 501x car once, but my tracks dont usually stock schumacher stuff so he had to have bought them online.

All I remember was them being light grey colored, and very hard.

The Kyosho ballcups seem to be 4,8mm and Tamiya ones 5mm. Do the Kyosho ballcups still fit ok?

Grey Tamiya ones are the same part number. No way to know when you order them if you'll get new or old stock.:(

Unless you call in and make sure, if they are even available separately yet.

But that is why I personally was thinking about ordering the Kyosho ones if they fit.

Grey ball cups came in my trf201 kit

5mm Reinforced Adjuster part no 54257
(Grey) available at rcmodel - just added yesterday!

Also Stella has got them in stock:
