Between limited slip and posi traction?

It may sound stupid but, I have heard many different answers.

Just looking for the full details on both.

Like whats the difference between the two.

Im not interested about the gear ratios or none of that.

Just simply what Limited Slip is.
And what Posi is.

 

As far as GM is concerned, they are the same thing.

 

Back in the 50/60's, when GM started selling a clutch-type limited slip differential option, Chevy called it by the trademark "Positraction". That name was typically shortened to "Posi" and stuck, and became a generic term for a limited slip differential. Pontiac called the same thing Safe-T-Trak... but no one ever uses that any more.

 

Alright this isnt answering my question.

Sometimes I see people that burnout where only one tire spins freely.

Others have it so both tires spin freely on a break torque.

whats the difference?

or technical term for those?

 

When one tire spins freely, the car has an "open" differential. It does not have a limited slip differential (Posi), does not hav a "locker", does not have a "spool" - all of those are methods for connecting the two rear wheels together so they can not slip independantly.

When both tires spin together, the car has a posi, a locker or a spool.
Your original question was "What's the difference.... between limited slip and posi traction?" Both Shoebox and I accurately answered that question.

 

Lol, I guess a different question should have been asked to begin with.

 

No you two gave me the history of them.
No reason to be smart.
I was just stating that it didnt answer what I was looking for.

 

Not "getting smart"........

Next time I'll know better than to try and help.

 

 

I beg to differ. Your original question was What is the difference between the two. Both Shoebox and Injuneer politely pointed out that the difference is basically brand/name/trademark. To put it another way, you effectively asked (unknowingly it appears) what the difference is between Coke, Pepsi and a Soft Drink to which you got your answer.

 

So, what have *you* been told is the difference between the two?
