E locker questions

I am looking for info on a 2015 T4R Limited AWD. Does not have an E locker and am thinking about installing an E locker or maybe just a limited-slip diff. but do not know how that would work with the way the AWD works?
I searched a few keywords but did not find anything as to what I am looking for.
Am I using the search the right way?

 

I would imagine adding a locker would have minimal impact on the awd system since you're going to be driving so slow anyway.

 

A selectable locker sill have no negative effect.

 

What is your intended use for the vehicle? Have you ever gotten stuck?

I would suggest you try some offroading before considering a locker. I've had no issues with my Limited. The A-Trac is a pretty awesome system and gets you out of many situations. I'd suggest raising the vehicle, and adding a bit of protection underneath, before considering a locker. Just my opinion.

 

You dont need a locker.

 

I would highly doubt you 'need' a locker. Unless you bash it off-road of course. A selectable locker is the best because there are no ill-effects of having a locker until you need it.
