    personally I have never ran red-line products in a rear differential before but I ran their syncro mesh and transmission fluid and I just loved it, I use to grind at high speed shifts from 4th to 5th at 89K on the car and now at 134K she still takes shifts right near redline 6,800. I don't do this often find you. and I tend to baby my car due to the fact that she is showing signs of a weak tranny. So in short I personally love and trust Redline oil products, and if you have a kind you know you can run in your diffs which I believe is the same as our tranny fluid (not sure though, haven't had to do much work on my car recently)

    Best of luck in your research.
