What kind of stress? How was the stress applied? What part of the housing cracked? Do you have available pictures of the broken pieces and your setup?

There are many, many ways to set them up improperly, causing increased stress on the components. It may be that we can identify the root cause of the issue and suggest other recommendations for resolving it without needing to replace the gearbox housings with a different design.

Short answer: No, there are no COTS closed* metal plate replacements for the ballshifter.

The long answer: You probably did something wrong if you broke it. The case is plenty strong. Loctite should not cause a problem because the case is made from glass filled nylon, not polycarbonate. Was the case exposed to impacts or something? How did you attach it to your drive base? Any pictures of your setup would go a long way toward diagnosing your problem.

We've used VEX ball shifters for roughly 3 years now and never had any issues with the housing. My first reaction is that they may be mounted improperly or are being exposed to external forces/impacts that they aren't designed for.

As others have said though, pictures would be a big help.
