How strong are aluminum driveshafts?

[90dpscoupe]

It came balanced for me, rode a little smoother, i would suggest a saftey loop if you have a high horsepower application, but thes d/s are probaly stronger than stock, the yoke is what i would think could fail or u-joint before the actual d/s did.

I dont have a saftey loop and imo, dont feel i need one unless im putting out about 375 hp. But they can handle a lot
