When would you need to spin one wheel rear? In other words, when is the automatic locking not useful?Because being able to lock it before you need it instead of after you need it is a better idea.
I think this is a decent answer, the auto-lockers are very abrupt when they engage.An e-locker will behave like an open diff under normal driving conditions making it more predicable. An auto-locker will go full lock with any slippage - in snow, icy, or slippery conditions it can be unpredictable.

I've seen certain competitors with the auto lockers and it usually activates in less than one wheel rotation. Even the Ranger's rear locker isn't instant, the pin has to find its hole to lock the rear and that requires spinning the gears in the diff.
That's fair. GM full-size trucks and SUVs frequently come with auto lockers. I guess I am accustomed to the Torsen limited slip in my ATS and how I don't have to think about its operation.There are no midsized trucks for sale in the US factory equipped with a Detroit (auto) locker.
You might as well just weld your diff.

GM & Chevy both use the Eaton G80 in the rear. They're good diffs but I've heard stories of them grenading when stressed.That's fair. GM full-size trucks and SUVs frequently come with auto lockers.

I know limited slips have serious disadvantages when off-roading, though.
Great information, I thought GM's midsized units had a auto-locker option.The Z71/AT4 package on the Colorado/Canyon come with the Eaton G80 rear diff.

Torsen isn't a true locker, it is better than an clutch pack LSD for off-road use but has its limits. I would have loved to have a torsen in the front on the FX4 package.
The G80 is an auto locker, but not a Detroit (or lunchbox) type. Detroit's use a spring loaded toothed assembly. A G80 has a spinning mass that uses centrifugal force to push a latch that engages the locking pin. From a durability standpoint, a lunchbox is much stronger. G80's because of their design are prone to fail. Both can engage abruptly as @Colo_Ranger mentioned and your average driver won't know how to deal with it.Great information, I thought GM's midsized units had a auto-locker option.
Torsen has the benefit of "no wear," other than the diff itself failing as there aren't clutches but worms gears.
Finally, I have head of all sorts of diffs grenading when stressed. I think there might be a greater propensity when the auto-locker is stressed and abruptly locks. However, the same is probably true if you try to lock your Ranger's diff and then floor it so that the pin engages under extreme load.
