What kind of case breakage have you seen?

The majority of case and extension housing breakage is going to all be related to how the chassis is setup.

I‘ve seen them explode. Aftermarket cases aren’t made because someone wanted to open a new market.

Lets not turn this into the thread equivalent of aftermarket blocks.

If you want to run a TF with big power and a stock case, by all means have at it.

I run clutches so what the converter crowd does has little bearing on what I care about.

Defending a transmission because of brand is the same as saying you can stay with the 8.75 axle even though the 9 inch is far stronger.
