    I bought this for a 2020 Ram 1500 classic. The additive seems to work but my rear end still makes an ever so slight noise upon sharp turns when accelerating, and when its cold. Now when I say it makes a noise you have to really listen for it and it only last 1 or 2seconds then its over with. And from what I have read this is a normal occurance for this type limited slip rear end. I dont remember it making the noise before the oil change, but I wasnt listening for it either, and after the oil change I was listening for it. So Im going to say its fine. The noise hasnt got any worse, and doesnt do it regularly.

    I had to replace all of the side gears, spider gears and clutch packs in my 8.8 Ford Trak-Lok. On opening the box I was worried about this products validity, as it did not smell like a rotting half dead cats peed in the box. The stuff from Ford typically does smell wicked awful. I went ahead and used it to soak the clutch plates ahead of time, and then added the rest of the tube to the gear oil as it went into the differential housing. It seems to work fine, the rearend has not chirped, clunked or barked a tire since.

    Installed new gears which I purchased here and since my 67 GTO has Safe-T-Track, it requires this additive. Works as it should, just pour the complete contents into the rear end prior to filling with fluid. This helps it mix itself when you add the diff. fluid (which I also purchased here).

    I use this and 3 quarts of Mobil1 75w90 LS gear oil in my 2002 Tundra. Without this additive, the LS clutches will chatter.

Trans-X Posi-Trac limited slip gear oil additive is designed to quiet chattering differentials and improve gear oil performance.
