Inference to the same question about Powertrain Industries Shafts. Carlos summed it up with what happen and that was like the first Group Buy set up by AlteredBeast ( Albert ). Like most anything new out for the car, they may or may not have flaws. Once this problems was found out, Powertrain got on it and fixed the problem. They have since had two more groupbuys after with no problems from what I've seen over the last year or two. There web site is very plan and does not show the AL shaft part number anymore, so call and check on this info. If you found that they do and don't sell that shaft anymore, please inform the this board of the info as well. As far as safer and better between the two. Well, sure the steel is stronger, little heavier. But the AL shaft is rated at 800lbs/ft Torque. So I cannot think of any tire holding that amount without spinning, even a slick. Bad side to the both of these shafts is, if such a break where to happen. You would be sitting right next to a steel or Aluminum saw blade. That thing will cut and rip right threw that center consol at some 8000+ rpms, because the less resistance from the rear diff, will send the rpms shooting way pass redline at the time of the break. Thus is the reason some spend 3 times the amount for the carbon fiber shaft. For it will only bust up into two splintered half's. But like many after the first GB, I have never had one problem with mine. I post pro's and con's on anything I buy. If it sucks, I'll post it, if it's great I'll post it. This shaft is an only makes sense part. All the benefits are there, no center bearing to replace anymore, more TQ handing, more power to the rear wheels, lighter than stock by far ( 12lbs ). Here's an example of stock driveshafts on BFG drag radials on 15psi tire pressure, ( Not Slicks ). Even thought this is a Supra TT's shaft ( only BPU ), the affect is still the same for us. 
That was a RPS Stg III clutch, BFG's and a 6000rpm lanuch. Here the part number on Z tt AL shafts 3191-504A ,,,,,, I think it was the 3191-504 ( no A ) was the first shafts made with the problems. Powertrain Industries INC
