THIS is the modifier you need and want to use if you have a 2004-2006 GTO w/the M80 rear diff...
GM stopped making and stocking everything for this car. It's extinct. Parts are sparse. But gratefully this little bottle of magic still exists, and is affordable! Change your rear diff fluid every 18-24 months or every 15-25k miles if you own an 04-06 GTO. The LSDs are a metal on metal "cone type" design, so the amount and quality of FM you use is critical, as is flushing the fluid frequently to excrete metal slush in the diff housing. A quality 75W-140 gear oil works very well. Start with 2oz of the modifier, then ~1.5-1.8qts of the gear oil. Drive the car around for a while and listen to how the rear end sounds when turning and performing slow-speed maneuvers in parking lots. Add 0.5-1oz at a time to tune the diff. Let me know if you found this review helpful. 👌 🍺 ✌️

It is a must for 2021-2025 Yukon's and Tahoe's in rear driveline oil!
Put this in my 2021 GMC Yukon Denali rear driveline oil when I changed it out and it took away the low moaning noise we had while turning! It is a must for 2021-2025 Yukon's and Tahoe's in rear driveline oil.

Genuine GM.
It is what it is. And its what GM says your supposed to use. so...Warranty satisfied. Gm's happy, im happy. I saved $300 doing the transfer and differential fluids myself. In my driveway with simple hand tools. And it only took 1-1/2 hrs. WARNING TO ALL! Make sure you can access the FILL PORT BEFORE you drain your fluids! Make sure you can fill what you just drained!!!! Or you are stuck. Best luck to you all. Check that fill port!

Must have when replacing rear end fluid in suburban
Used this with GM original rear end fluid to resolve the rubbing noise we were getting with our 2021 suburban. The dealership couldn't figure out the issue but luckily came across a youtube video that listed this additive as something that would fix it.
