I agree with Mike. I've broken TWO heavy duty half shafts on street tires in the past year (yep! you read it right HEAVY DUTY). The first one was at the track and the second one was doing an evasive maneuver on the street to avoid getting hit by a senior citizen making an illegal left turn from the far right lane. Fortunately I had enough momentum from the sudden acceleration to get past the impending doom, but I busted the half shaft which in turn took a chunk out of my differential.

There was a post here on the board a few weeks ago where somebody likened the half shafts to fuses in an electrical circuit. The only problem is that the stock ones are not rated high enough for the kind of abuse they might be subjected to(like putting a 1 amp fuse in a 2 amp circuit). I would much rather replace a half shaft than a tranny, but I think there is some leeway for heavier duty half shafts. I also installed half shaft loops this time to avoid the damage that can be caused by a broken half shaft. Luckily, both of my incidents were at fairly low speeds.
