    I see all articles saying "The 2016 TRD Off-Road version is fitted with an electronically locking and limited-slip rear differential"
    I'm confused.. so the rear differential does both limited slipping and locking?

    or does it mean LSD on the front and locking on the rear...?

    If 2016 Tacoma Off-Road version is equipped with front LSD and rear locking differential then I'm all in...

    Rear LSD and front locker would be more likely if it's all mechanical.
    But odds are it's simulated (Electronic via ABS) LSD with electric (Mechanical) locker on the rear with an open front.

    Thanks. If I want a real off-road capability but not wanting a front locker, do you think getting a Detroit Truetrac will be a good idea?

    On a budget it would be OK, it takes some changing of driving habits to run an auto locker on a daily driver.
    And ARB is a better choice if you want your truck to drive exactly the same as it did before.

    Thanks. Btw, Truetrac is an LSD though (not auto locker). But as Rock Lobster said above, if it'll get ABS-LSD at the front then I don't think I'll need one since that simulates a mechanical LSD.

    I could be wrong, but I'm pretty sure the A-TRAC system is front and rear.

    Isn't A-TRAC pretty much and ABS-LSD?

    Oh yeah, a locker is no doubt the way to go for serious wheelin'. I was just trying to help clarify for OP (and myself) that the front diff isn't always open, i.e. when ATRAC enabled.

    Basically, you can get it in ABS-LSD mode up front (ATRAC) and lock up the rear diff...as I understand it. I think its even possible to go into 4x4 OPEN front and back, but who would want that!?

    I respectfully disagree.
    Lockers have a small advantage over a-trac in soft conditions where you want the tires to dig down, but when climbing loose rock or dirt a-trac wins.
    Plus, you can press the rear-locker while in a-trac, locking the rear diff and disabling the A-trac till you're through the obstacle, press the rear diff lock button again, unlock and be back in a-trac.
    Not only was I able to climb out of a gravel pit that a rubicon couldn't by using a-trac vs his lockers, I was able to strap him out.

    So, is it possible to run with ATRAC enabled while locker engaged? Or is the front diff going to be open when locked up in the back?

    You can't have both at the same time, as locking the rear diff disables ABS, and therefore A-trac. so while both front and rear are now locked, you lose the A-LSD operation or the ABS. If one of the front wheels is in the air it will spin and take all the power without the ABS to reign it in.

    what does this even mean ? real off-road capability. cripes

    electronic brake controller limited slip is absolutely just as much 'offroad worthy' as some
    clunky mechanical one. in fact it's better for a ton of reasons on a vehicle that also does
    grocery/highway duties most the time.

    same tires same clearance same entry and departure angles, same weight distribution...my electronic brake controller will go
    anywhere your mechanical will go, and even more places, since mine is programmed to do even better kung-fu


    whatever...the pissin match between electronic and mechanical should just be over already...it's 2015 for craps sake
    and no one is getting dysentery on the Oregon trail last time I checked

    If we're going to get in a pissing match, I'll take the bait and state that my preference for wheeling is front lockers with LSD rear.

    ahh you are gonna get stuck someday anywhere other people have gotten stuck no matter what you run

    just run with a buddy with tuggin straps, or have a winch, or come-along ready is the only thing
    that really works all the time

    Toyota hasn't been listening to their customers again. They have yet to put a dig unit in the transfer box of the Off Road model! I can't believe it won't go into front wheel drive when I want it to! Disgusting, Toyota!

    I can't believe it! It's been 20 years and still no dig in the transfer box! Ancient technology!

    So have I. Engaging the rear locker disables ABS, so A-Trac is disabled. When you unlock the rear, ABS is re-enabled, and A-trac is functional again. You don't have to turn it back on.
    I have an 09 DCOR, and the rear locker lights and A-trac indicator do not come on at the same time. The A-trac light goes out when the rear is locked, and it comes back on when I unlock. Does yours act differently?
