Yeah, there nitrous shafts i think come with a warranty.

 

Closing on 6K on the dyno....

 

You could always go with carbon fiber. If they fail they turn to dust instead of sending shrapnel up your ***, and they are way lighter. However, carbon fiber shafts = $$$$$

 

I think Golden has a point. Carbon fibor is the way to go, but **** its expensive.

 

I think carbon fiber is a bit overkill, but I would invest in a driveshaft safety loop. I couple of years ago I was working on a friend of mine's Pro Stock Truck, and we broke our brand new Jerico trans. We borrowed a Liberty, but the driveshaft length wasn't the same. I just called a local driveshaft company in Houston (this was at Houston Raceway Park) and had one made for around $75! It worked fine for what we needed it to do.

 

What happened to your weak dyno's? I didnt think you had enough power to break anything. Did you get any numbers?

 

What's the diameter of that shaft? Is it the 4" 3/4-ton piece? If so, I need to get me a new shaft.

 

Scream did you ever install it? Your buddy might of hooked you up with the wrong piece

 

Nah...both of 'em are in the shed at the house. Is there a smaller aluminum shaft?

 

I blew mine ....



I went with the Nitro 1350 from a company that used to be call Thrash out of San Antonio...it cost me including transfer yoke about $300 altogether. Great people over there...real nice owner. Had my new shaft built in 1 day and shipped to me (East Coast) in 3 days. They go under the name driveshaft specialist inc now. It may be heavier than the stock or not as strong as carbon fiber (900 to 1500 bucks) but it'll do...got a drive shaft loop now. So I'll put a bigger rear end if that goes next and like 02denali I'll do the 4L80 swap when the trans completely goes as well.

Good luck!
