If you are have the problem with 2 different brands then something isn't right on the car. Check that you have the proper length turnbuckles; if the turnbuckle is threaded in to far they pop off easy and if they aren't threaded far enough in the ball cups break or bend.

Both Associated and Losi make heavy duty versions of their ballcups that are a wee bit stouter than the stockers. And while the RPM ones are likely the best on the market, durability-wise, it would still be my educated guess that whatever it is that's breaking the stock ones will also lead to breakage of whatever else you use or something else on your truck.
My advice would be to clean up your driving, because I can't see that AE would have let a built-in failure problem slip between the design cracks and out the door. I've always found it funny that at the club level how many people have such problems, breaking things left and right, and yet you go to a bigger race and literally no such problems.

That seems counter-intuitive to how it should work, or at least how they're intended or designed to work.

I use these as well. I also have used the Losi white ball cups and the J Concepts ones as well with no problems. If you don't pop them off much they will stay tight and not come off.

Another problem is to make sure you don't have metric ball studs with American sized ball cups or vice versa as that will cause a problem for sure.

I use the white losi cups with the Losi titaniun ball studs. I drill a hole in the top of the ball cup so you can remove the ball stud and install or remove shims for tuning with out popping the cup off. It works very well.
This is on my T4.

I know this guy and his ballcups kept popping off at vineland. That's why he posted.

I also remeber another guy i race with broke a ti tierod with a kyosho ball cup. I the gweed did it too cause i gave my 2 spares to them. It happens but that just shows how good the rpm cups are.
