Where to get a front Torsen Differential installed in a F150 non Tremor/Raptor?

Bringing this all back around to friction modifier – the actual function of modifier (the “modification” it makes to the friction) is that it brings the static coefficient of friction down to a similar level as the dynamic coefficient of friction. This helps smooth out the transition from static to dynamic friction, getting rid of the tendency for abrupt stick/slip. This, as a result, largely eliminates the chatter or squeak . However, it does this at a price – the price of lowering the coefficient of friction for the whole system.

So, if we return to the notion that the differential is a friction device, it then stands to reason that the friction the differential generates is directly influenced by the lubricity of the oil blend that is used in the system. If the oil’s friction properties are reduced, the amount of friction that the diff produces is proportionally reduced. That, in turn, has the same affect on TBR. Usually, it is a small but measurable amount, maybe up to a 10% loss of TBR.

Awesome, so the friction modifier is being spec'd by Ford to just be on top of NVH. There is no risk for premature wear or failure like with a LSD that is a "clutch type". It's not a reliability thing and why some don't see the need to run it and why Torsen told me it isn't required.

I was thinking your take was that there was actual substantial slippage in the gears, like one could rotate on the other (cogs could "ratchet" for lack of a better word) and not that the faces of the cogs will be forced into each other and that "slip" due to lash and transferring power from one gear type to the other causes a noise as part of normal operation.

So when I install a Torsen, I'll use a friction modifier or a Fluid that has it, so I can have the best possible driving experience with no real side-effects.

Thanks for sharing!

Torsen locker for the front ordered up! Very excited to get this in before the snow is all gone.

Interesting note, you can save some decent coin, by ordering up the part number from a Raptor, instead of getting the Ford Performance version. CL3Z4026E

This part appears to be about $1k USD. Is it cheaper in CAN?
