Do i have steel or aluminum driveshaft?

Potential at top speed is well after 115, it takes forever to climb higher. My tires I run, I run at least H(130 mph) or V(149 MPH. Never maintain those speeds because these trucks are bricks with horrible brakes. The moving around them in triple digits feels scary. Stopping them at that speed, good luck

Im back and have a picture. A magnet sticks to it. Is it aluminum or steel?

Steel. Aluminum doesn't oxidize like that (it will oxidize, just it won't turn brown) nor is it magnetic.

Has anyone ever heard of these breaking?

Plenty of videos on YouTube of guys doing dyno pulls and losing the driveshaft. Taking a truck much past where the limiter is would be foolish.

The breaks I have seen have been at the u-joints and not the shaft itself. But trying to push high speeds, you do risk it

I'm smelling a lot of potential injudiciousness in this thread.....

Do you have steel or aluminum driveshaft? Magnets will not stick on aluminum.
