Yes and Yes

Actually, the first link the ad says its a G80 and an Auburn posi, which the picture isnt either. The posi has clutches, not cones like the Auburn, it looks more like a Ford Track Lock.

The second picture is a gov lock.

 

[readymix]

I can see the clutches. Unless I am not understanding you correctly.

 

[K5MONSTERCHEV]

An auburn posi (like in the diagram)has cones that go into the case and bite, when they wear out the case is all worn away, thus making them less diserable bcause they are basically disposeable, you cant rebuild them.

The one inthe picture has clutches and a big S sping, when the clutches wear out you can take it apart and replace them.

He says calls it an Auburn and a Gov Lock, its neither.

that 11.5" govlock is pretty burly

 

[broncoman6524]

so the first one is NOT a gov lock and the second one is?

Yes. The first one is a limited slip of some kind. It looks like the factory limited slip my bro had in his camaro. Bottom is a Gov-loc.

Oops. I did not see the pics when I looked at the first one last night. I only saw the graphic at the bottom.

It really looks like a factory Positrac. Does not look like Eaton or Auburn. It def aint a gov-loc.

Yeah, thats why im tayin it looks more like a Ford Tack Loc because of the big S spring. GM posis have plates against the side gears and 4 small springs. Thats what you get with ebay.

GM also used the S spring on Positrac units. I put one in a 10 bolt with my brother. Readymix even rode in it and we thought we blew it up.

Oh yeah yeah thats right on car 10 bolt posi's. I was thinking about 12 bolt, where they have the plates and 4 springs.

I know very little aboot 12 bolts only that they have 2 more bolts than a 10 bolt.

I suspect those (S-spring posi's) are Eaton units as well as the 4 spring one, too lazy to go dig up the car manual and see what GM called it. They are stock, but only seen them in cars.

I had one of the S- Spring units in my 83 GMC Jimmy 10bolt. Looked just like that. Far as I know, it was a factory item. It blew up after making some horrific noises for awhile.

Alright, anything other than full-size trucks.

But you are right, see these in the 7.5" and 8.5" 10 bolts, but never seen one in a full size truck.

Of course, I know the GM full-size truck manual shows a limited slip Eaton unit for the trucks, but never seen or heard of one in an '80's truck. ( which is what the manual is)
