Hedge, I think you are right about this.Sorry, but all indications are that it does not have a Torsen differential. The owners manual specifying a friction additive seems to confirm.
I'm hoping it's not a conventional clutch type and I don't think it could be in the front. I also hope it's not an open diff with traction control.
Here's a comment from a Four Wheel Parts test of the Tremor: The front axle is a Dana Super 60 that now, for the very first time, has limited-slip differential boosting traction to the tires. That diff is a Spicer Trac-Lok specially developed for the Tremor. It’s been designed with a lower “torque to rotate” according to Dana, so it should react more quickly. It also uses carbon composite clutch plates.
Here's a link to the Dana Trac-Lok page: https://spicerparts.com/press-release/dana-introduces-genuine-spicer-trac-lok-for-aftermarket
If that is what it is, great. A gear system. But it also appears to have thrust plates. I don't know about the actual Ford requirement for friction modifier in the Tremor front diff.
