Yezzir, most helpful. I was going to upgrade my axles, but I got scared off by the notion that if I do I might grenade my pinion instead. When you say a "standard set of chromoly shafts" you mean something like Ten Factory shafts?
Yes, just standard u-joints and nothing exotic like RCV's. They have really really strong rzeppa joints and you'll break everything else before you break them. Trust me, I have seen it.
