I dunno about that, I drive a 66 chevy year round through WI winters and even with 420 lbs of sand next to the tailgate I have found myself going down roads sideways till the right rear tire hits the curb or the gravel on the side of the road... nothing you can do really. intersections can be outright horrible when the roads were plowed AFTER the snow has already been packed down. and it does not help they don't allow studded tires here.
one thing I would like to say that I don't think any1 else said is the tranny and its affect on the rear end. I have a shift kit, and it does NOT help with traction in the winter. when you are accelerating from 1st gear at an intersection the nice positive shift we all love in the summer can be enough to kick the vehicle sideways in an instant in the winter, its bad with a one legger, and its worse with posi.. I never thought about it till I found this out when it happened to me and I found myself in a corn field facing the direction I came...
just something to think about...

I don't know if they all do it, but mine does and I know it is a posi 'cause I've had it open. If I spinn them faster then they lock together. If your Blazer is the 4x4 model, I heard they all had posi's.

I've only read the first page of replys. My appologies if this has already been addressed.
How can you tell what kind of diff you have without opening it up? The guy I bought my blazer from said it had a locker in the rear but when it is lifted up the tires still spin in opposite directions. Do posi's behave this way? I know opens behave this way and I thought that lockers do not. The limited slip in my Firebird will allow me to spin one wheel without the other moving when in the air. I heard from another person (who is usually just talking out of his ***) that a locker (maybe a posi) will behave like an open when in the air but if one tire is held, the other will be locked in with it. This is the scenerio with my Blazer. I no longer have a vehicle with a known open diff to test how it behaves in this situation.
Sorry if this has already been addressed. I'll find out when I have time to read this post tonight.

I'd replaced my spidergears and such my first try sucessfully.... though i was only 16 at the time I put a Power-trak in my El Camino when the posi fried... it was going fine till i learned the hard way why reving your motor to 6500 in neutral and then slamming it into L1 wasn't a good idea (shredded the trans)
As long as you know how to follow directions you should be fine, if you can find it Horse Power TV did an episode where the put one in a car...

You know how Kleenex is just a brand name for a type of facial tissue?
Thats how the name Positraction is to limited slip differentials.
The easiest way to install one is to swap out the entire rear axle with another one that has it in there. Otherwise you risk an opportunity to learn all sorts of details about shimming and how it relates to ring and pinion gears. Takes an experienced hand to do it right and avoid whining or excessive wear from the gears.

I have a few questions about posi. They might have already been answered, but just want a better understanding. Thanks
1. my 85 gmc is used as a daily driver pickup. Which would be better for it, posi or limited slip? Im looking for something with a quick start and nice burnouts.
2. My axles are probley from 85, should i replace them or will they be fine. They have suffered alot of with only one wheel spinning.
3. Which brand of posi/limited slip would be the most easiest to install? Ill be the one installing it.
My rear end is a 8.5, 28 spline. Also i want to keep my 3.73 gears.
Thank for the help.

Having a posi track in my truck which has NO weight in the back end, it can be kinda scary. Hotrodding it is fun but i spin tires on accident alot too. In the rain i dont even drive it. Everytime i get on the gas when its wet i completely lose control. Other than that its fun leaving 2 strips of rubber when all my buddies only do 1.

My first car was an '87 Caprice SEO (cop car) with, as I'm told, positraction. It was definitely slow going around curves in the snow & ice, but man it was fun in snow-covered parking lots & dirt roads in the summer time.
Anyway, I know very little about cars in general, so I've a few questions:
1) Is positraction considered a type of limited slip differential?
2) What, in your opinion, is the best choice for winter-time traction? What type of differential (is that the correct term? lol) would be best for maneuvering around icy, snowy city streets?
Right now, I have a '92 Grand Marquis and since a new car is out of the question, I'd like to give my current one some mobility in the snow. Suffice to say I get honked at sometimes when trying to get going & move through an intersection after having stopped at said intersection.

At least that's my favorite. I just love turning sharp in a paring lot and the tires go chirp, chirp, chirp
-ps- a posi more than doubles the avaliable traction... just something to keep in mind.
