Approximate cost

Hey Gents,
Im wanting to upgrade my 2018 F-150 Supercrew non LSD with a 3.73 LSD. My question is how much would I be looking at and sometime in the future I would like to do the front as well. My truck only has 50k on it and I don’t drive much but do like to do off road sometimes which why I’m asking. Thanks for any information as to what parts and possibly where to get it done as I’m not that comfortable with trying to do this myself.

I don't know the cost, but I would highly suggest saving up until you can afford to do front and rear at the same time.
If the differentials have different gear ratios, you won't be able to use 4 wheel drive without most likely damaging something.

the 4wd is useless unless both ends have the same gear ratio

I was not aware that there was LSD available for the front axle?

I interpret his sentences as LSD for the rear and just a matching gear ratio for the front.
You can do a front locker on offroad rigs....but I am not aware of a front LSD either.

This is what Ford offers in the Raptor as an option. It fits 8.8 front axles.

Ut's not the parts that are expensive, it's the labor. It'll probably cost $2500-$3000 total for front and rear.
