Handy source of quality OEM friction modifier for my new limited slip differential. Used with 31 spline 8.8 ford lsd carrier using carbon fiber clutches originally on 2003-2004 ford mustang svt cobra.

Great additive for older vehicles with sketchy, noisy differentials. There are other uses reported by various commenters - read what they have to say. Even though packaged in a secure container, the smell seeps out of the bottle, and you and your family will know it quickly, if you bring it into your house. Store it in a garage or outbuilding to avoid the smell. (The strong smell means it will work very well.)

Smells like death but works great! I used it in my 2005 Expedition limited skip rear end and it worked great. No chatter or groans in the rear so it’s doing what it’s supposed to.

A mechanic buddy suggested i put this along with a quart of Lucas stop slip as an affordable attempt at fixing the slipping in my 2004 Honda civic auto tranny. Still slips a little but so much better than before. Amazing. Hopefully it lasts till I can save up for the rebuild.

If you have a LSD with a spider gear and clutches, this is the modifier that you want to use with either 75W-140 or 85W-140 gear oil...

This is a must for a clutch style limited slip differential. It says it's to quite the differential. Ford requires/recommends you add this to oil in differential. Only one bottle is required.

But it seems to be working along with Lucas Transmission conditioner

put this along with lucas gear lube in a 2013 f-150 rear end that prior to this service sounded for all the world like it was going to explode at any time. Other lube changes with other products made no difference, but this combination solved the issue completely.

What can I say bad, official Ford friction modifier that is necessary for the rear end in my Mustang.
