Anyone use Ford's Friction modifier in their rear ends?
I've had people recommend them and have heard good but few things about them.
They're also very inexpensive, and readily available!

Any comments would be great.

TIA

 

their pretty good, i work at ford in parts, we use it a lot. it smells horrible haha. its good stuff though, motorcraft makes it, does a good job at it as well. if its what you have available get it, if something better is available, get that

 

what's that supposed to mean?

 

heh yeah, whats that suppose to mean?

Yeah, its available to me, but I want to know how good it is and if anything else is better for the same or better price.

I'm planning on changing out my LSD fluid so I'm looking for some suggestions.
Looking to put Redline 75w90 (as thats readily available also) and wondering if I should put some LSD additive to it. I know Redline says it has some LSD additive already added to the 75w90 but I've heard from some local guys that I should add some of that FORD/Motorscraft LSD additive also.

 

i would get the Redline Lightweight Shockproof, no need for LSD additive, and its better than their 75w90 for the rear in my experience. i meant basically that, if you haveredline available, get it, the ford stuff is good if you dont have access to really good stuff like the redline.

 

ah, i'm just gonna use royal purple on mine. Racing beat recommends it so i don't think it could be bad at all.

 

do these make your LSD more stiff? My car has about 60K on it now and I think that the LSD is getting worn...
