What is the best weight gear oil to run in a 12-bolt chevy rearend?

Great gear life... Torco 75-140 GL-6. Just my 2cts.

Do you want to go fast? Or maximize gear life? That would be good to know.

Hey Angelo let's say the quickest gear oil for a 12-bolt?

Redline Super Lite Shock Proof

I’ll second that. Use it in my stocker and bracket car. Never a problem. And easy to get at the local auto parts store. My Orielys stocks a couple bottles.

Any 75w/90 synthetic

Dave is right, Superlight shock proof will work well in rear set up correctly. Full disclosure, Red Line sponsors our race teams, but when thinking about what oil to buy and what companies to support, I think it is important to look at that. Red Line isn't the only company supporting drag racers, but when it comes to gear oil, I don't think there is a better product.

We use all three gear oils, super light works well in our stick stockers with 12 bolts. In the super stocker, we run the heavy due to weight, clutch, and HP and have seen a difference in gear life in that car.

Any questions, just ask or stop by at the track.
