REAR LOC's

I heard having a LSD is about the best way to go. Cheap...don't wear out...and does good in snow. Or, you can spend about $400 more and get an air locker or something like that. I am probably going to get an LSD when I fix my truck and buy a motorcycle.

What kind of driving do you do?

If its more of a street truck, then go with a LSD. It will be a little price since you will need to get the gears re-set.

If its more of an off-road truck, get a lockright. Automatic locker, unlocks when it needs to, CHEAP CHEAP CHEAP, does not require setting the gears again.
I can get into this alot deeper but I would like to see your answer to my question first.

yah it really depends on what your plannin to do with the thing

Hmmm, 2wd, I'm guessing on-road. Get an LSD

I have a Detroit EZ Locker (not in, cause of regular driving) but I'll stand by them. Centrifugal lockers can get a little shady going around turns in the rain or snow. Not big on optional lockers(air/electric) cause lines can get cut or snagged.
