How long on stall of these from ta performance

For the cost compared to a new rear, it's cheap insurance, and you can do it yourself.

What weight and do you think synthetic should be used for differential fluid

I have the Ultimate 10 unit with axle tube braces, good piece, cover went on in just a few minutes. The axle tube braces require a tab to be welded to the axle tube, the other end gets connected to the girdle. Looks really sharp. What ever fluid you choose make sure you add a bottle of friction modifier, in my case I didn't have it on hand at the time and the rear was noisy on slow tight turns, all good now.

ordered the low profile ta performance one today. how is the install on ta performance is there any special tools or anything. and what fluid does everyone use ?

I'm using Lucas with additive. Basic hand tools along with something to scrap and clean the mounting surface. I also use a can or 2 of brake/carb cleaner to make sure that the seal area has no oil on it when I seal things up.

80w90 gear oil ? or 75w140

 

[JimP]

go with the 80w90 with the gm limited slip additive. I had a lot of diff chatter when turning without the additive.
