When to get a stronger driveshaft?

At what HP/TQ level should the stock steel driveshaft be replaced in favor of a heavy duty one like Spohn's?

I don't think I know of anyone who has broken the stock steel driveshaft. I know a few people have broke the stock LS1 aluminum ones, they usually just get replaced when they break. I think the weak link is in the U-joint. It is kind of small and most people replace the shaft and go with the bigger Ujoint when they upgrade to a 12bolt.

I think when you start running a full slick you may want to at least run a loop.

when you run a full slick and start cutting come 1.6 and better 60 footers you'll want to change driveshafts.
