Torsen diff and 4.10 gears on XLT?

[dpatt711]

I have a 2021 XLT 4x4 5.0 max tow with locking 3.73s and I noticed on the Ford website when my vehicle is selected it shows a torsen differential and 4.10 gears available, is that something that can actually be added or is the website just not programmed to filter correctly?

No, 4.10s are raptors gears. Yes you can add them, not as a factory option, but you can do it yourself. Same for the torsen, a few members have swapped to torsens. I know the 5.0 is lacking in torque against its siblings, but gearing is more than enough that 4.10s aren't warranted vs 3.73s.

Yeah, these are the parts its showing me. I just didnt know if my truck had the 31 spline front axles, or 8.8"s that it says is necessary.

Somewhere we have a thread that has all of the part numbers -- more than one thread has this info.

You usually add or do anything as long as your wallet can handle it
