How exactly does a locker work, and what does it do? Is Moser or Auburn better?

I'd stick with a Detroit locker or an Eaton posi, but that's just me.

There are gears/springs/whatever inside that basically lock together under a load to force both rear tires to spin at the same speeds. when coasting, decellerating, or under very light accelleration they aren't locked and it'll allow the outside tire on a corner to spin faster than the inside tire (the driven one).

check out this website for information on differentials. http://auto.howstuffworks.com/differential.htm

this site has lots of good auto information on how stuff works.

I believe it was eaton who has come out with another ttype of a locker

u can also weld the spider gears together and make a spool

vfast

not on a street car dude

yeah, what vfast said. Only weld the spiders if you like the ditch.

but isnt that kind of the same idea as a limited slip.....locking under more force?

horatio102

They're similar - the main difference is that a limited slip allows a difference in tire speeds, anywhere from 2:1 out to 4:1 or so, and a locker allows for no difference when engaged. Standing on the gas in a sweeper with a locker would most likely result in the inside tire breaking loose and spinning, possibly spinning you right into the wall/ditch, whereas a limited slip would still allow for a difference in speed and you wouldn't have nearly as much stability problem.

In a street car I'd go with a limited slip. If you're just going to be dragging it though, a locker might be better for you.
