Lockers are very rugged. Used mainly for rock crawling, racing and serious street situations. A locker is basically like having a spool in your truck, that disengages when you let off the gas. Anytime your foot is on the gas both rear tires are turning the exact same speed. Even if your in a turn each tire will turn the same speeds, meaning your truck will bind a little and your tires will squeel a little in turns. But also both tires will turn with full engine force.

With a posi, most are clutch driven. That means one tire will have 100% engine force, but the other one may be recieving as little as no power or as much as 100% power. So a posi rear end may not lay 2 strips of rubber every time you spin your tires.

I picked a locker because I'm sure i'm gonna have traction problems. 4.10 gears with 3.06 tranny 1st gear. Plus a 450lb/ft engine. I also drive pretty rough sometimes. My truck is also built pretty racy, so i t hought that would fit better than a posi. When it locks up it hits pretty loud, which I think is cool, my dad has other thoughts.

Either can be good or bad, like i've said a million times, it all depends on what you want out of your truck.
