RPM Hub carriers

[Jacks9930]

Is there a larger pivot ball for the true track RPM hubs? The reason I am asking is bacause I had the ball pull through the hub a couple of times.

No, there are not larger diameter pivot balls for the revo. The RPM carriers are known for the pivot balls popping through due to the pliability of the plastic, there is a mod you can do with the steel rings from the traxxas carriers but you have to purchase the carriers to get the steel rings or make your own rings.
The Traxxas carriers #5334R are a better option over rpm IMO.

I wish I knew that before the car twisted the MPI shaft in to a boomerang

I machined up a set of steel rings to press over the ball carriers - haven't had one pop out since & I've had some real big stacks.
Need a lathe to do it tho.

That's odd... I've had my true tracks on my revo for 2 years... haven't had one pop through yet. I've had one of my front ones pop through, but only once or twice.

It may have something to do with how tall you have it setup to run.

You can purchase the race rings off Egay.That should take care of your problem.
