Default Drivetrain weaknesses??

I did a quick search and it looks like some of the internals of the torque tube and half shaft (whatever that is) will need to be replaced under high HP. Besides the 4l60e which I know needs to be rebuilt, what are all the possible drivetrain upgrades that are necessary to safely run 500rwhp with consistent drag racing and have 0 concerns? Can someone give an estimate how much $$$ these upgrades will be?

I've gone through torque tube, and both output shafts. Car already had hardened gears. Not sure about the half shafts, they may be next. My car dynos 515 at the wheels.
