Rear diff swaps
i have a 2016 F150 crew with a 3.31 and I am wanting to swap for a 4.11 posi. Has anyone did this and is there anything a person needs to know before, where and what you need to buy?

If you have a 4x4 you will want to swap the front too. To have my local hotrod shop do this sort of thing it would be about 1500.00 and well worth it as the gears have to be set up properly with backlash, pattern, etc... or it will fail in a few miles. I would contact your local 4x4 high performance shop about this for particulars - you may find it not worth it.
