JK front axle LS?

I am getting a JK unlimited - probably an X.
Going to get lift/tires/gears. While I am screwing with the gears (4.56) I am thinking about adding an LS - probably trutrac - up front (assuming a D30 27 spline).

Would an LS up front screw up the ESP or any other computer related stuff?

I beleive that new D30 has a bigger spline than 27. 30 spline or 32 spline I'm not sure.

Carrier is the same, it is still 27 spline, the outers are 32 spline. I talked with the Detroit rep at TDS, he said the diffs are the same, you might need to drill out the bolt holes because he said they were 7/16 instead of 3/8.

Why would you want LSD up front, when you already have a perfectly functional electronic limited slip - which handles much better then a mechanical LSD off and on road.

Not sure but I was under the assumption that the traction control system with electronic limited slip was only in the rear axle. Again I'm not sure about that.

Electronic limited slip (part of the traction control) runs both axels AFAIK. And it apparently works quite well. I would think that this makes the mechanical limited slip in front to be somewhat redundant. Electronic stuff should have none of the handling drawbacks as well.

It comes with it from the factory - all trims have traction control, that includes the brake activated electronic limited slip functionality.

If they make one that will work in the new JK, go for it It'll be an improvement over the esp

A truetrac has no bad on-road characteristics. It is invisible, you can't tell its there. There are no drawbacks.

Indeed - with electronics taking care of it it will never be activated.

(Seriously though, I do not know how they will interact - who will run first, but after observing how the brake actuated stuff works, I would not care about mechanical limited slip at all. When brake actuated is not enough, you already can make use of a a full locker..)
