OK, I'm just kind of on the edge here. I'm about to swap front diffs here in a few days, and I thought if I was ever going to go with Longfields now would be the time, but I'm just wondering. Do I really need to spend the money for them? I don't rock crawl on any regular basis and my wheeling is mostly moderate, but then you never know what I might do.

That said, I really, really don't want to change a birfield on a cold rainy night in the middle of nowhere, although I do carry a spare just in case. And I'm kind of thinking that that my 5000lbs truck with 35s is probably just as likely to break a birfield on a moderate obstical as a lighter Toyota with smaller tires on something harder.

I guess I just need some convincing to go ahead and spend the money. Should I get his treated axles too?
