1962 positraction lube/additive ?
I just had a posi built for my '62 and am wondering if there was a different additive for these with no fabric on the discs. It is all original parts, no aftermarket, except the new clutch packs.
My builder said to just use what is/has been available, but thought I would see what the people with these posi's are using. I will be using standard oil based gear lube. Thanks

The GM limited slip oil additive is still available and works pretty well. I like the Ford additive better. It works well with problem differentials like the Auburn. Sometimes 2 bottles of additive are required.

I'm liking what I read about the LubeGard being formulated for cone and steel clutches.

All of them are. GM has always had steel clutches and cones in their cars and trucks up to somewhere in the '90s. Chrysler too. Ford used clutches with fiber lining and still does.

I know Pontiac posi's were cones, but all the 12 bolt posi's I've worked on had a combination of fabric and steel plates.
The LubeGard is about half the cost of the GM additive... If it works just as well. Of course, they claim it's better.

All of the factory installed Eaton Posi units in the 12 bolt and 8.2 10 bolt had steel clutches, 18 discs and 200 pound springs in the standard units and 22 discs with 800 pound springs in the heavy duty units. After market Eaton Posi units today have carbon fiber lined clutches, 14 discs with 400 pound springs. The Traction Lock differential in the 8.5 corporate 10 bolt had steel clutches. GM used the Auburn cone unit in some of the 8.5 rear ends and all of the 7.5 car rear ends that got the limited slip differential. Starting in '90 the 8.5 in the Impala and Caprice got the Auburn. The truck Eaton locking differential had steel clutches until sometime in the '90s I believe and then went to the carbon fiber clutches. All of the old Chevy '55-'64 rear ends with limited slip had steel clutch plates. The Buick, Olds, Pontiac 8.2 rear end had cone Borg Warner differentials. The '04-'06 GTO also had a Borg Warner cone differential. Torco oil is the only oil that will work in these GTO rear ends. GM has been dealing with steel on steel for a long time.
