Placed my order a couple weeks ago for a 2012 Eco. It comes standard with electronic locking rear. What does this do for me good or bad compared to my current non electronic. I know one thing it does is cost a couple hundred more. Unrelated, but on one of the posts a guy said he'd order one if his wife would allow him. My wife said I didn't need one since my 2009 has 11,000 miles and not a scratch in the bed. That's all I needed to order a 2012!

 

After living with a limited slip in my past three trucks I am very glad to see a rear locker come from the factory. This ensures that equal power is distributed to both tires. Limited slip is a clutch/friction system that work okay, but seemed to wear out over time for me. I would have to cheat and use the brake pedal to get it to work sometime....

I am expecting it to help reduce the number of times my new truck gets stuck!

 

when its not engaged your have an open differential.

when you shift into 4wd and lock it both rear tires should spin with 1 front.

unless you go off pavement where you might need it, there is no benefit what so ever.

 

that's not quite right... anytime you might get in a situation where one tire will spin while the other just sits, a limited slip or locker can help. off road is not the only time that happens, just the most frequent.

 

yes, but you CANT use this locker without being in 4wd.

 

I'm interested in this two. Seems the Elocker works great when in 4 wheel drive, but what about the other 90% of the time when you're operating in 2 wheel mode? Wouldnt the limited slip be of more use the vast majority of the time for most people? Less hard core off road ability compromise for extra traction when not in 4 wheel drive right?

 

That's the way I see it!

 

That's dumb that it doesn't work in 2wd, my 2011 Powestroke works in 2wd up to like 25mph or so.

 

So does the Raptor.

 

you can make it work in 2wd using raptor components which cost about $150, do a search in this section and you should find it.

to me, having an open rear end doesn't bother me enough to justify it right now and i don't want to start modding this truck until the warranty is out.

 

Do the raptor switch conversion and don't look back.....

 

For every on road situation, I'll take the LS over Ford's elocker. It works at every speed. It works immediately. It works in 2WD.

Traction control systems are getting better, but LSD >> locker for on road. Each person must decide how much off roading they do when the elocker would be a benefit.

 

keep in mind, on the new f150's (2011 and up) the traction control system will work as a "limited slip" on the open rear ends....the wheel that is spinning will have the break applied and the other wheel will be transferred power.

there are youtube video's that were done to demonstrate this. having an open rear end in a new f150 does not mean you will only spin one tire in low traction situations, it just means that the brakes and computer will act as the "limited slip differential" so to speak. then, when you want to lock it in use the e-locker to do so and go.

it's the best of both worlds, on road and off.

 

wrong post

 

I wonder if it's just a cost saving measure by Ford.
