Quick question
 

My traxxas cvds keep poping out of the rear with a truetrack setup. will the 5153R Inner Drive Cups fix this?

Ive been using the true track with no issues for the past several months with no issues. Can you post some pictures of the issue. It seems as something may be stretching the drive shafts further than usual, or is it possible that you bought the true track for a different model than what you have, by accident.

anything is possible. I bought the truck used and it came with it on. I alreadt changed the cups and it seems to work. But i did not change any thing else so i will get photos and maybe you can see somthing i missed.

just use the extended drive cups and it should work.
