I did not know that either. I knew stock was open or LSD but thats just from reading here lol

 

lol took me a awhile to figure what i had, why can't the glove box just say LSD.
i'm guessing this is better then then the open one, for burnouts.
i think open diffs help w/ turning, one wheel spins more to keep traction.

 

Not true, Limited slip only applies power to both wheels when it needs to. Hence the the name limited or anti slip. When just driving on a normal basis only one tire has power to it.

A locker on the other hand is locked perminitely, again, hence the name. Those are little jekry around corners.

 

I suspect after that last comment I might have a "locker" in mine. almost everytime i take a sharp turn it feels jerky at slow speeds. What do you think. how can I find out. I bought the truck used. it is not in 4 wheel drive mode when this happens.

 

This isn't really correct. A limited slip is just an open diff that clutches the axle shafts to the carrier. Both wheels receive power until 1 doesn't have enough traction then all power goes to the the slipping tire.

A locker is not locked all the time, an auto locker locks when sufficient torque is supplied.. Selectables of course can either be open or locked full time.

 

doesn't it need power to both tires to go straight?
sounds like ur saying on the highway you only need one tire to maintain speed.

lsd locks somtimes right. open is worse, but why?

 

I hate open it sucks I can only ever get my right tire to spin and thats y my right tire has less tread lol Maybe if I stop power braking it all the time ha yeah right

 

Read my post. Both wheels have power. LSDs never lock, they are just open diffs that clutch the shafts to the carrier/ring gear to add some resistance to one-tire-fires. Open diffs find the path of least resistance, once 1 tire loses traction, all the power goes to that wheel, same thing with an LSD except the clutches provide a small amount of resistance to that but not much IMO.

 

+1 on EVERYTHING Hahns5.2 has said!

I TOO HATE the word POSI!!

 

Thanks for clearing that up!
