So how much punishment can stock half shafts take? I have heard that they were used on many drag racing set ups and the real concern is the strength of the u joints, not the shafts...

[/QUOTE] You can get 3 1/2" steel half shafts if you really are putting out some very serious HP.

[QUOTE=Gale Banks 80]  I see that they are not for the 80 to 82 Dana 44 Rear. I would think that as small as they are they wouldn't be much of an advantage over Aluminum. I'm still wondering what it would take to use C4 Half Shafts.[/QUOTE] My advice is to speak with VanSteel directly 1-800-418-5397. I spoke with Dan Dorsett. Or also just e-mail them with your questions...that's how I started off with them. They are very nice people.

YES THEY ARE HELPFUL, EITHER SPEAK WITH DAN OR HIS DAD ART. iHAD MY HOLE REAR END AND FRONT END DONE BY THEM. HEAVY DUTY HIGH PERFORMANCE STUFF. NO PROBLEM WITH MY 500+ PONIES.

I received my wife's Christmas gift............it's from me to her.........my carbon fiber half shafts. They weigh a little over 6 lbs. each with the Spicer universals, all taped up. The tape has to way a little............I hope she likes them, or am I in trouble...............................AGAIN?????? 

By the way the half shafts were made by PST, it's marked on the CNC hub. They were shipped from Van Steel.
