TX Unknown brace/strut

Can anyone identify what this is called and maybe where I could get one? what is the purpose of it? Its the cracked brace/strut bar. It makes a loud knock noise every time I takeoff and its really annoying. If y'all could Identify this it would really help thanks.

It sounds like you are talking about your PPF? It's the thick beam that runs from your transmission to the rear differential (hogs head). If that's what you are talking about take it off and get it welded/repaired at a machine shop and save yourself some money.

Not sure if you can get an aftermarket one, maybe someone else can chime in.

That's just the underbody cross brace, the rear one. They're a dime a dozen used.

The car will drive fine without it, but it's there to add stiffness to the chassis.

There are a bunch of those available from forum members since it gets eliminated with our diff brace. You should inspect your PPF for cracks at both ends, as that is not a piece that typically breaks, it would take a pretty hard hit from the PPF to snap it. That much movement in the drivetrain usually means there is something else broken.

I am saying that chances are there is something else broken if your PPF has enough movement to cause the aluminum bracket to snap.

Remove the broken bracket and see if you still have noise when you take off. Do you have a lot of movement at your shifter?
