Friction Modifier Positraction Additive for Limited Slip Differentials

I thought my car didn’t need it, but after I changed the differential oil, the warning light came on. I have to buy it.

Worked really well with new Yukon gears. No noise. Recommended by Yukon Gears.

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.

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

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.

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.
