I've been scanning the web for info on the front differential, but it seems there is not much info on the front diff for the 2020's. Does anyone have part numbers for Detroit Lockers or ARB's for the front end? I felt the front limited slip did a good job in the slop on muddy roads, but it didn't lock hard on climbs out of creek beds and on tire lifting rock gardens.

One of the TFL guys mentioned the front diff in a video, don’t remember which one, said it was a Dana. Made it sound like it had been around awhile.

Probably the same dana 60 that's been in there forever. Probably has a re-branded eaton truetrack LSD in there. I'll peek at the stamping the next time i'm under there. The model designation is usually stamped on the pumpkin.

There should be some options it's a Dana Super 60. I would not want to be the test guy for aftermarket lockers for the 2020, but the guts should be the same.

I have looked at a lot of different sites but not been able to confirm.

Has anybody heard for sure which type of limited slip is used up front on the tremor?

It’s a big mystery. Lot of questions and no answers. I keep hoping someone will pop the cover off and look at it.

I can't complain about a Dana limited slip differential front end. Dana makes well known and respected differentials.

I believe its an open diff that uses the vehicle's brakes on the slipping wheel so it can send the power to the wheel with traction.

It definitely has a Dana LSD front diff. The wheel brake locking thing you are referring to is part of the Traction Control system which you can turn off with a push button above the Sync monitor. It does work well with the limited slip diff but it is not a part of the differential.

Good info to know, thanks for the clarification. I didn't think it was part of the differntial just work in conjunction with it to achieve its limited slip.

The Dana limited Slip Differential will work without the Traction Control System and vice versa. They do not rely on each other. They are completely separate systems. One does not require the other to work.

Is this what you are looking for sir? Has anyone installed this yet and what is your opinion?

This is the front axle (open) in my 2020 F-350 - XLT 7.3L gas

Ford Dana 60 (unlike the Dana 60 of yore) with Ford logo on the cover

35 spline axle shafts

short reverse open diff

ring gear diameter: 10 in.

28 spline pinion

I'm not sure, but a True Trac torque biasing, gear driven limited slip fits the Dana 60 front diff with 35 spline axles.

They are transparent in delivering traction to the wheels with the most traction, not the least like clutch type limited slips, and go to full lock across if detecting no difference in side to side in resistance. Great on the front axle. My Dodge RAM Cummins has them on both ends.

only real way to test that is if they are side by side .... since you can just turn off the limited slip in the front
