Friction Modifier Positraction Additive for Limited Slip Differentials

Fixed clutch chatter in a Dana 35 trac loc LSD even though I put in synthetic fluid that was meant to have friction modifier for LSDs in it already.

It does just what it's supposed to do. I've used it twice on my Positrac 1972 Monte Carlo rear without an issue. I just added it to one of my bottles of gear oil before pouring it into the rear.

This is the correct additive for a positraction rear end assembly in a car or truck. Use the entire container amount when refilling the rear end assembly. This product is a good value for the price.

This product is the real deal. Works beautifully to eliminate binding positrac differential.

Works as it should but smelled strongly in packaging..don’t leave in the house!..lol

Replaced the diff oil with valvoline synthetic in my tundra and immediately got severe chatter while turning at low speeds. The lsd additive in the valvoline oil didn’t work at all. Added one bottle of this and the chatter went away.

I would have never guessed that 4oz of an additive could make such a huge difference. My 'Cuda has a 3.55:1 Auburn posi in it. Even though I use limited slip gear oil, it would chatter and buck when I would turn the car. It was embarrassing and worrisome when I would back into or out of a parking space because it was so loud. Auburn is known to have issues of this type due the their clutch cone material.Added the full bottle into the read end and I was stunned. Before I found a parking lot to do figure 8s with, to mix it up and work it in, the rear end was already quiet. At speed, the car would feel somewhat rough... that has been eliminated.It worked so well that I was worried the posi would slip, so I found a vacant road to test it. After three fast starts, all of the marks showed exactly the same start and stop of tire spin.
