I don’t personally drive in snow much at all here in TN, but how will the new Tremor perform in the snow with the limited slip front differential? Will the Tremor be a turn off to those in snowy climates? I’ve never driven a front LSD equipped vehicle before, so I’m curios on everyone’s opinions.

I think the front should have been a locker. Like RAM has on their Power Wagon and Jeep on the Rubicon. I think this was a miss on Ford's part.

Depends on what kind of limited slip it is. If it's a gear driven limited slip like a Truetrac or Torsen, then it will feel just like an open differential until one tire starts to slip and it will then transfer torque to the wheel with greater traction. A clutch type limited slip keeps constant pressure on both wheels to make them spin at the same speed, so it would be interesting to drive in the snow.

LS shines where you have varied CoF because it constantly transfers power back and forth between the rear wheels.


Lockers on the other hand are at there very best when max traction CoF is available to both wheels. Think Moab Utah!

If you dont mind me asking what was your average cost to add a Detroit Locker (parts and install labor) to a SuperDuty?
I have thought about upgrading from the factory LS (E Lock wasnt an option on my 2WD DRW).
A locker would be a beautiful set it and forget it upgrade,
Thanks

Mine was around 700 plus 100 for new carrier bearings and shim kit, I did the install myself, but a shop should charge more than 3-4 hours labor.

"I had a truck spin out driving in hard pack slick snowy conditions because the limited slip differential locked when the truck downshifted going up a hill."
I had that happen last February. I slid off the road and hit a post which caused enough damage to ruin my Toyota Tundra. 20 year old truck with 80,000 miles that I was going to keep forever. This is no joke. What you described is a real hazard. If someone had been coming I would have had a serious problem. This happened in Bozeman, MT in some of the most slippery conditions I've seen in 50 years.

Since this thread came back from the dead, let's talk about what a waste it is that Ford only offers two options: open or locked. How many people really take these 8,000 lb. vehicles off road and play in rock gardens? Yes there are a few, but what percentage? 1%? So for 99% of people who pay extra for the rear locker they can never use it. Can't use it on pavement wet or dry. Not good for snow unless the snow is DEEP. So the locker just stays off all the time. I'd be willing to bet that 99% of Super Duty owners never touch the button the entire time they own the truck. So the locker is just a waste. Now, if Ford put a limited slip or TorSen diff in the rear, THAT would be useful. Automatic, seemless, and no damage if driving on the street. Would be a huge benefit in snow, rain, gravel roads, etc. I will never understand how they screwed that up so bad.

My thoughts as well, I would never put a selectable locker in the rear of a vehicle for those reasons. An auto locker is the way to go because it give you the extra traction all the time and still unlocks so you can turn.

As someone that uses the locker quite a bit(I used it yesterday I’m deep mud for example) I would trade it for a limited slip any day. From November to February the roads where I live are icy and slick. The limited slip is much better in these conditions. Without it I have to use 4x4 more than I did when I had a LSD.

Sire you can. I use mine on wet roads quite a bit to prevent the one tire fire when pulling out into traffic. The Toyo tires I had were worthless in the rain. The Michelins I have on it now are worlds better. And the locker is great for the steep gravel driveways I’m on every week.

The locker is extremely useful on stiff suspensioned vehicles like the Super Duty. It's surprisingly easy to lift a tire off the ground even on moderate terrain, and the limited slip these trucks come with is almost useless.

On another note, the new 2023 Tremor finally has a decent helical front limited slip, miles better than the junk Dana Trac-loc clutch type.

I’d take the selectable locker every time over the limited slip. On uneven ground It has much quicker response than the 4wd does. I use it quite frequently.

The factory LS on the 10.5 differential under my 2007 F-250 wasn't the greatest anyway. It was better than an open rear differential, but not by much.

Not sure if this was mentioned but, if you ever upsize your tires, but not your spare, E-locker for the win. No worries about wearing down your differential while driving with one smaller rear tire...
