Geez, I don't get why you guys are so worried about what he does with his truck. He had done it in an enviroment where he wouldn't hurt anyone, so who cares if he wrecks his truck. Doesn't affect me in the slightest. But I will say thank you for the research and hopefully this belittling of an individual does not prevent people from making other discoveries or researching. Wonder where we would be if people didn't test the boundaries.

so basically, dont make a stupid mistake and toss a jack stand under the axle, instead be sure that where you place it, it wont damage anything if she does roll off of it......stupid fixed.

That's exactly what it did. But my point was it wasn't a digital change, it was very controllable. Much more than I expected, and controllable enough that I could stop with it half off of the jackstand.



That's why I was careful on where I placed the jackstand.

As far as the question being answered by others, I'm the type of guy that likes to see for himself. If it's easily do-able (and really this took me 5 minutes when I got home from work), why not?

Not only that, but the aforementioned youtube videos don't have a wheel in the air, so they didn't answer my question.

The only thing I'm regretting is bothering to write a post about it.

My only regret is you didn't film it.

Think of the opportunities. It goes well and we learn something. It goes poorly and you get famous on the internet. Win-win!

Lol. It is a neat idea and I would have really enjoyed seeing it working.

Reminds me of the Dad's "choice" Ferrari at the end of Ferris Bueller's Day Off.

(Yes i know that was a brick holding down the gas pedal, not exactly the same situation we have here.)

I may have something to offer here. I've posted quite a bit about how much I love the Truetrac. So much to the point that I bought a leftover 2014 without the locking differential option on purpose, and then installed a Truetrac in it.


Someone may ask WHY? We have an F150 with the ELD, and have used it a couple times. Works great. But since it disengages over 25 MPH in 2 or 4 high, and is most useful in 4 low, which I rarely use, except to pull out a stuck buddy, I opted for having a mechanical limited slip that works all the time, at any speed, in 2 or 4 high, and 4 low.
The results are...The truck drives exactly the same in every way, and the rear traction control/one wheel spin control Hardly ever has to do anything, because the truetrac takes care of the spinning wheel before the TCS even knows what's going on.
Secondly, in 4 low, or rock crawling situations where one wheel may be severely unloaded, or off the ground, a very small amount of traction control braking, (much less than without the truetrac) will transfer almost full torque to the other wheel, almost as if you had a locker, and you WILL move forward.

The reason why the Truetrac works so well with traction control is this... The truetrac has a torque bias of approximately 3:1. That means it transfers about 3 times the torque (resistance) of the spinning wheel to the grabbing wheel. The TCS by itself one has a 1:1 bias. So when you have a wheel in the air, (the only situation where the truetrac doesn't perform well,) the slightest bit of traction control braking with transfer 3 times the amount of torque to the traction wheel, than the TSC by itself would. You essentially have a locker.
Basically, what I'm saying is, it's the best of both worlds. You have almost absolute torque transfer, the TCS doesn't have to work nearly as hard, thus saving your brakes, and staying cooler, and it works all the time with no driver input needed.
To sum it up, with traction control and a Truetrac, I have not been able to spin just one tire. May be possible, but I tried, and couldn't make it happen.

Everyone has there own preferred way of doing things. This is the first E-locker of have ever had, and I think it works great. When you are in extra slick conditions, that thing is worth it's weight in gold. in "normal" slick spots, the "traction-granny" E-posi works just fine. when low and slow- flip that thing on, and you can climb a wall(reminds of the '76 F150 I put a detroit locker into- w/o the "issues" that go along with it), while the rest of the time, it's a mild mannered DD/GG/errand runner!

Just making the case for Truetrac because the OP brought it up.
Nothing wrong with the locker. I loved the one we had. I guess part of my problem with it is the limitations FoMoCo puts on when you can use it. I'd rather make that call myself.


If the comments I made suggest that a locker is junk, unnecessary, a waste of money, doesn't have a purpose, or anything else, I wasn't. Just expressing the good points about the Truetrac, because as I said, the OP brought it up.


Also, another good point to the Truetrac is if you buy a truck without the E-locker, (whether it be used, or a deal you couldn't refuse) its an easier and cheaper option, with similar results.

I already have the elocker in the rear and am seriously considering a trutrac for the front when I do my gear change.

driver444

I had a front and rear Truetrac in my 2008. It was nearly impossible to stick that truck, (within reason of course) and that truck didn't have traction control of any sort.


My advice... Do it. With the TSC, it'll be awesome. The only thing is, unlike with an open front differential, on snowy roads, with all 4 wheels pulling at the same speed, it's a little easier to get squirrely, where the truck with the open differential will have a "dead wheel" to help keep you straight.
I loved my 2008. I love my 2014 too, but it still has to earn my respect!
