I have a 96 s-10 blazer 4x4 --- 4.3 vortex --- 4door--- with a GU6 rear
end (3.42) and want swap the rear axle assembly complete for a G80
(limited slip) same gears.
What other year and models possible have the 3.42 --G80?
I want to get rid of the extra tire slippage in 2-drive when in snow
and on gravel.
Thanks

Hey mailman. I have limited experience with 4wd vehicles. But I have a
friend who was almost fired from his job at a dealership (asst. sales mgr.)
when he accidentally ordered, for inventory, 4wd vehicles WITHOUT limited
slip. I would think that it would still require a special order (if now
even possible) to get a 4wd with open differentials. I've been in & around
vehicles all my life; and the consensus seems to be that people would prefer
a 2wd with limited slip than a 4wd with open differentials.
So, here's the question: Are you positively sure that you have open
rear ends(differentials!)? I'd check them, physically/mechanically, before
I took the options-label's "word".
HTH & hope it saves time & expense. You may already have what you wish
for. s

Why? Limited slip in snow is a PITA. It makes the rear end so
squirrely if it is slippery. I have only had one vehicle with limited
slip. It was a 4x4 pickup. Once it started snowing for the season, I
had to pretty much leave it in 4WD to keep the rear end from walking
around to the front.

It wasn't due to a heavy foot either. I am a fairly conservative
driver. The limited slip just made the rear end attempt to compensate
for the slipping wheel and it would start to move sideways in an
instant if one hit some ice or something.

I was told I wouldn't like the limited slip rear end, but I didn't
believe them. After getting it, I had to admit they were right.

Now that said, being as it was limited slip on both ends, in 4x4 it
would go just about anywhere.

Sounds like your a glutton for punishment. You do know that the G80 diff
is a known failure item right?
That said there is also a reason why it has 4x4. If your driving around
on loose gravel or snow use 4X4.

What fails on the G80's? CLutch packs?

I don't memorize option codes Steve, but is the G80 the same 8.5"
(approximately) unit in 4th gen F bodies? And what other models use it
off the top of your head?

Thanks,

Same POS.
It is the Eaton Gov-Lok unit. GM and Ford both sell it in vehicles. GM
has 3 axle options IIRC, open diff, limited slip (GovLok) and on the
real hard core machines they do offer a Detroit locker as a special
order item.
The G80 came in the 10 bolts and the 12s.
GM used it as the primary upgrade in towing packages for the truck lines
and in most of the F bodies as well. I think Ford uses it in the lighter
trucks and the Mustang as well.

Thanks for the reply. I think that's the unit that uses a pinnion
shaft and cam mechanism to squeeze the clutch packs when the axle gear
speed difference reaches a certain point. It seems like a good idea in
theory, but if it isn't durable then it's pretty worthless.

The Eaton uses a set of weights that swing and clamp the clutches when
the sides have different RPMs.
The unit that uses the pinion shaft to lock/unlock is the older
Positraction unit that is the same as the new US Gear units or Eatons
conventional units..

Thanks Steve , Don't know if I'm a glutten for punishment or not. But
also have a 93 with limited slip that I use everyday turning around
and backing up, whether it is starting out on gravel or snow or backing
out ,very seldom do I spin out or get stuck, and when I use the 96, I
am constantly spinning a rear tire to pull out, or putting it in 4x4 to
back out when in snow.

The G80 is NOT a real limited slip. It is a flyweight controlled clutch
activated locker. It locks when there is an 80-100 rpm difference
between the two sides. The problem is that they have a nasty habit of
coming apart. Seen them bust the spider gears, shed the carbon off the
clutches, the pins holding the weights break and toss parts around
inside. Not my idea of fun. Before I put a G80 in I'd spend the money to
put something like an Auburn Pro in.

I drop my 94 into 4wheel when we get snow or flooded roads or if I'm out
in the woods in the mud. Figure as long as the surface offers some slip
I have the extra drive axle for a reason. Same routine with the 2002.
