Do you prefer locking diff over limited slip
My 17 has the locking diff. Never used it but was told by a few you have to be careful when you use it on a slick surface it can cause the truck to slip sideways. I always had limited slip before and just need to know more.

I love it and find it very useful - limited slip is not an option on the SD so choice is that or open diff which the locker is def better than an open... LOL.
When you don't use it, you have a kinda built in limited slip differential in the sense of the traction control which applies brakes as needed plus cutting power to transfer power between wheels and limit wheel slip. Either way, the locker is nice and when you put it in, it disengages the traction control which I find to be an added benefit.

I've had to use it on the road when hitting intermittent black ice in the mountains. Worked great. Just watch your speed and no sharp turns if on good road.

I had LSD in my 1996 Ford Ranger 4WD. That worked amazing. I rarely had to use 4WD with that truck. My 2005 F-150 supposedly has LSD according to the window sticker and the axle code. That thing doesn't work for crap. I've spun out one rear tire in loose dirt/sand on a flat, smooth forest service road. It's beyond worthless to the point that I have often wondered if someone forgot to build my axle correctly.
In any case, depending on the quality of the LSD, it may or may not be better than the E-locker available on the SDs. I'll be anxious to see how my e-locker does in comparison is those [extremely] light duty off-road conditions.

I’ve had and used an elocker on a super duty. Now have LSD. They both have their uses. The LSD is a small hammer and the locker is a big hammer. Neither is right for every situation but I prefer the LSD because it’s easier to use in more situations.

Thanks, Had limited slip always before and never thought I needed 4x4 under my conditions. I always said if it is that bad I will stay home. Limited has always worked well for me but will see how locker works when needed

My 2005 diesel had a LSD 3.73 ratio. It worked well in most situations, worked even better when I changed the oil and used a bit less friction modifier in the oil.
My 2017 F350 diesel is a locker. I find it works well, use 4*4 and locker for pretty good traction, in or out of a situation. My only beef is when trying to get out of a bad situation and wanting some speed it shuts off at 30 mph which I Think is too soon.
The real limiting ting factor is the tires.
