Adding Torsen Diff

[Burns363R]

Im looking at buying a Torsen diff to a used 2021 tremor that wasnt ordered with it. Can anybody help me find the OEM ford part number from a truck that already has one? I found the diff on ford performance, buy my dealer says they cannot buy from Ford Performance. I told them they should be able to buy the diff as a regular replacement part from Ford, but there parts guy isnt able to find it. I dont have a vin from a Tremor that has one, so its kinda tough to track down.
Any help would be great.

Thank you,

Well - with a few members going through adding a Torsen front differential to our trucks I thought it would be wise to consolidate information in to one place to help each other out! The Ford Performance part number is M-4204-F150LS which is confirmed by Torsen directly to be the correct part...

Ford Performance M-4204-F150LS F-150 Torsen Front Differential 8.8

If your F-150 needs added traction on muddy or snowy roads this Ford Performance M-4204-F150LS front limited slip differential if the perfect solution.

What those guys said (and in my original thread as well)!

I imagine you might make the Ford dealership's head explode when you explain this - but the shop I used got it handled with no issues when I got them the parts.

From that original thread it looks like the 2 part numbers for the bearings have been combined into one.
You need 2 of these?

So with nothing on sale, your looking at $710 for the torsen and then another $175 for the bearings.

Thanks for the replys guys. I ended up buying a 21 Tremor yesterday with 11k miles. Didnt get the deal done on the Torsen, so I will do it myself later.
I will be posting more around here as I get deeper into this truck.
Thanks again

If you hard core wheel, spend the money and get a pin locker. The Torsen's not a deal breaker unless you wheel a lot, but for $500.00 it's a steal.
