I ordered it. I tow as well. It was $390.00 retail. If you want to get moving quickly on wet roads, it would be a great help. I think I read on the ford site somewhere it disconnects automatically when over 50 mph or when in a really hard corner at slow speed. The old limited slip did not seem to work right when I needed it most. & 4 wheel drive binds on dry surfaces (gravel, not pavement)even on gentle turns so that is not always a good option.
Rear Differential Electronic Locker
The 2011 Super Duty adds an electronic locking rear differential for the first time that’s similar to the GKN-supplied e-locker that’s available on the F-150 FX4 off-road package and SVT Raptor.
Brewer said the e-locker has been designed by Ford and will be manufactured at the Sterling Axle plant for single-rear-wheel F-Series Super Duty trucks only.
The locker can be controlled with a dash switch. It’s best used in low-friction scenarios, such as on slippery boat ramps or in slick mud and on icy roads. It will stay engaged until the truck reaches 30 mph, at which point it disengages until the truck’s speed returns to 30 mph or less. The truck will also disengage the locker if it’s making a tight radius turn by sensing the steering wheel position, so the rear wheels and tires aren’t damaged from scrubbing on pavement

Hmmm.... I couldn't disagree more. Boat ramps, slick mud and icy roads are better suited to 4X4. The E-locker just sends me sideways in these environments.

The first time I took my truck to one of the farms I couldn't get up one of the hills so I thought it was a great time to try the ELD.
I tried as slowly as possible and the rear tires only spun and hopped the back end. Put it in 4x4 and idled up no issue. The ELD has it's uses in other sceneros.

4 wheel drive wth two open diffs means 2 wheels actually driving, with limited slip, the rear might be a bit better, with ELD both rears can drive up to a certain speed. I wish my 05 had it, but i have LS. Its not as effective. Like rickatic says, when towing or loaded, its a huge increase in traction. I would order ELD front and rear if i could. You will find a stuck f350 is dificult to get unstuck. This keps you out of that, it is an option for 350 sounds like a smart order item.
