I was talking to some friends who own the 2015-2020 f150 and there seems to be some confusion when it comes to LSD. Im not even going to pretend i know anything about it but its good to learn things about my truck even though ive owned it for 3 years(embarrassing i know).
So the million dollar question wise members, do we have LSD?

nope, open only or open with E-locker.

I think some people call it LSD but I haven't seen the proof that it exist.

Ford discontinued LSD a while back and replaced it with an electronic locker.

Base models are always going to have open differentials (no LSD or locker). Some option packages include the e-locker. In 2016 at least, it was available with the FX4 package or the MAX tow package. I for one have both packages and therefore have the e-locker because one of those packages include it. I think the e-locker is available in different configuration in other model years.

We need to change our terminology while discussing these topics for modern vehicles I believe.
LSD means Limited Slip Differential. While Ford, to the best of my knowledge, does nothing at all internal to the differential (except for the physical hard lock), the vehicle itself does have limited slip characteristics.
So if the exact question is do we have limited slip differentials, the answer seems to be a definitive no (until I can see the differential with limited slip properties).
Does our truck have limited slip characteristics, yes.

Some of us are old and call new things the way we knew them in the past.
I still turn on my radio but my truck really isn't a 'radio' as much as I'm turning on my media center.

Figured I'd get this answered before the thread has to close up shop.

It's not like the answer is in a secret book that is in a secret compartment on the truck. Wait, wut? It's not a secret book, and it's in the glove compartment? Get out of here!

This thread gave me a high school flashback......

Whats this secret book you speak of? I could totally look but it sounds like the answer i seek isnt in there because it doesnt exist, my buddy is adamant we have it though....

2014 was the last year for a limited slip, in the f150s. The biggest thing i miss from my 2014, besides the color. "Flame blue". I have the E-locker. Its my understanding that must have the E-locker. Me personally i would rather have the limited slip. The E-locker releases around 27mph... at this point you only have a open axle...

While we're on the subject, as someone new to owning a truck - why does Ford choose to offer a manually locking diff and not an LSD? Wouldn't an LSD be more "automatic" and suit a larger number of drivers? Or do they figure the traction control acts like an LSD most of the time anyway? Just wondering because it seems most Chevy trucks I looked at have an LSD.

The feature I miss the most from my 05 Lariat is the LSD diff, I’d take that any day over the traction control in my new truck. It worked instantly unlike traction control that sometimes doesn’t do anything until it’s too late.

The limited slip is basically automatic and at any speed. The E-locker only engages when you pull the ****. It will stay on until you reach around 27mph. Even when turning. I made that mistake once.
E-locker is more popular for the extreme off roader. The raptor always had the E-locker. Like wise people like it for pulling a boat out of water.
the limited slip is what im more use to and used in sprot cars and muscle cars
