    I was very skeptical on how well this could work in an off camber situation, so I put myself in one yesterday just to try it out.

    I was on steep hill (about a 50 degree incline) and went in between two deep ruts up the hill with 4LO engaged (rear diff NOT locked). Only my front left and right rear tires were touching the ground. Once the tires lifted my forward progress immediately stopped and I started spinning without A-TRAC. I stopped and pushed the A-TRAC button. Once I engaged A-TRAC and got to about 2500 RPM's I could here an actuating noise and the truck started climbing. :eek:

    This is in a stock truck with stock tires on a muddy hill. Amazing.

    It does make a disturbing noise, but it works well. Almost like having lockers F & R. I wonder how well this feature will work with larger tires and a lift?

    ***UPDATED WITH A FEW PICS***
    I still need to go back sometime to get some shots of the spot where ATRAC worked so well.

    x2 Luni cruised this spot at URE in his truck (stock 09) with a-trac where I had to back and get momentum.

    a-trac is basically like a limited slip diff for all four wheels. Pretty unbeatable for something that is actually just "vaporware" and not additonal hardware

    It's a pretty cool feature, I've used it a few times as well. I also like the DAC on some of those decents, although a little weird to remove your foot from the brake pedal when heading down a big hill, oh and talk a bought a lot of noise.:eek:

    One more thing remember to turn off the RSCA when your on those extreme off camber deals, you don't want the side curtain air bags going off.:eek:

    I prefer 4 Lo and low gear over DAC. I tried kicking it on for a loose decent and the steering got squirrely as the wheels intermittently locked up. I felt more in control using the brake pedal. But on solid stuff it'd be great.

    My only concern with DAC is that at least with ATRAC once the brakes heat up the system times out and deactivates. Not so good with your brake dependent downhill control.

    I wasn't gonna dis on your photos, haha but now that you admit it :) Either way, you got some mud up on the tires and on the sides, I know how friggen impossible it is to get these trucks dirty. For some reason even in 4WD and doing everything I can to get the truck dirty, this is all I came out with:

    So what does that ATRAC mod do exacly? Bypass the abs so you get traction to the wheels that are ON the ground? Just wondering, it might be my next mod.
