I was reading that this was used in race applications and some people said that it quieted down their rear ends. Anyone use it? Its description is very odd so I wanted to see if anyone used it!

wat do u mean quiet down the rear end. ive nevr once heard mine it shouldnt be loud

I would not recommend it for use in a Traction-Lok rear end, from the specs I suspect it would be so slippery that the T-Lok clutches would not grab properly--sort of like filling the rear-end with friction modifier...

I gave them a call and they said that I would have to fill my diff with some extra modifier just to protect the clutches. You may be thinking of something else? Has anyone actually used it?

Sometimes they make a slight whine when you replace them with a new set.

That is odd in light of this bullet on the linked page:

• Not recommended for most synchro applications due to the product's extreme slipperiness.

Usually that caution is expressed when the lubricant is so slippery that it would make synchro rings (and other clutch type "things") slip excessively.

Here's another vote for "gears don't whine when properly installed" too...

Well they were professionally installed by a person that has done over 50 gear swaps. regardless I am not buying a new set of gears as it makes the same noise as the stock ones did. I am just trying to get them silent.

Are you sure you are not confusing normal RWD American car rear-end noise with bona fide gear whine?

I tell people that our cars are basically 1/2 ton pickups with flashy bodies; a bit better than the earlier generations, but you can't expect too much in the NVH department...

lol! I dont think so. My grandpa had a 69 and a 71 stang, those were loud. Its just a slight hum over what my old 98 cobra had, maybe a little louder then it was before the swap. I ordered some after talking with the rep and he assured me that it was less slippery then their gear oil. It has 3 percent friction modifier while they usually are 5. I am adding .54 ml of friction modifier (did the math.. haha) to bring it back to normal. Why it is too slippery for synchs is that is has any friction modifier. Plus it is thicker then most so that it wont flow through the channels as well.

Good lord you are making me feel old, I had a '69 Charger Daytona (440 with the 6-pack)--that I bought brand new...

[edit]

Let me add that I have been driving RWD vehicles for nearly 48 years (it will be 48 on Saturday, I got my first car when I was 14) and if the rear-end on a car/truck/whatever is noisy (by that I mean noisier than should be expected for the specific load range/gear design/etc) then the gears are either well-worn and due for replacement--or not adjusted properly.

We used to put sawdust in the gear oil (tranny's too) when trading in a car that had problems--works wonders...
