How exactly does the FX4 e locker work and how does it stack up vs GM E80?

So I know the basic difference between a locker and a limited slip. I understand the GM auto locking rear doesn't have to be manually selected, but I don't believe that it would be the optimal option for a lot of on-road snow and ice driving. A limited slip is better for that.

How does the new fx4 locker work? I understand you pull out the **** (like doing fog lights lol) to lock it in 4hi or 4lo. Now this seems impossible, but ford's website calls it a limited slip e-locker. That would probably be the best solution IMO, limited slip all the time and selectably lockable. I assume they actually mean its a selectable e-locker and when not selected its open diffs?

For many peoples uses it seems to me that if they are open diffs (like i suspect) when not locked, any other trim line f150 with a limited slip would be a better option?

It may be the locker Auburn Gear puts out. It is limited slip when not engaged just like any other ls rear ends with a clutch pack then when engaged it electronicly locks, for a better explanation you may look up Auburn Gear, I think its listed as their ECTD locker if memory serves thats the Electric Control Traction Device. I know thats what I want to add to my '08 down the road

Correction its the Electronic Control Traction Enhancing Differential I would have edited my last post but couldn't figure out how, this forum isn't quite like the last one I was on.

Can anyone else confirm this or provide more info?

Field scout, if it is like the auburn ectd, I think that is far superior to the gm auto locker for 99% of users. Limited slip always active with the option to selectively lock it off road seems like a perfect combo to me...

i can comment on the limited slip function. yesterday out on my street with the traction control off i put the truck up against a curb and power braked it a little bit and both tires spun like hell. i know some limited slips are weak but this one seems to be strong-for now

Sounds impressive. Now all ford needs to do is add an on demand setting to the transfer case like the expedition has...

What it sounds like is a limited slip that has selectable full locking.

From what I gather with the GM locker it spins until a certain criteria and then locks. I'd take the LSD/ selectable locker over it any day.

The G80 will engage in 2wd, it engages at 200 RPM difference. I went from a 03 FX4 w/ a LSD to a G80 and the G80 was night and day better, I have not used a e locker as ford has it set up however, I can say that I like the e locker set up except that you have to put it in 4wd, someone will be able to figure out how to how to make it work in 2wd I'm sure. I like my G80 in that I get 100% lock side to side pulling out of a boat ramp without the binding of 4wd. ever try to turn a wheel on brushed concrete without water on it? I'd like to get a XLT with the E locker but no such luck. I think ford has a great setup, the only other truck to offer a good locker set up is the H3T which has e lockers front and back (that is in this price range).
