What is a Tertian Response System? It sounds sort of out of this world.

You guys are way ahead of me here.

Is there some link where I can read about it?

 

That would be a smart phone typo terrain response.

 

I would agree on going aftermarket on the locker; not because of the factory lockers eating themselves (I think we have that condition diagnosed now) but because of the difficulty of the install.

As for the effectiveness. I don't fully disagree with bbyer on this. The LR3 does remarkably well sans locker. My LR3 is equipped with the HD package, but I've been wheelin' with plenty that aren't, and the difference is pretty subtle, really. I think the best way to describe it is that the open LR3s use traction control a whole lot more, whereas the locked-LR3s use the locker. My traction control hardly ever engages.

Now to the air-locker vs. e-locker argument: I have in the past pined for having a manual locker so that I could pick and choose when to engage it. That all ended last summer when I was off-road with an FJ Cruiser. Many times, the driver failed an obstacle, backed up a few feet, engaged the locker, and re-attempted it. As for me...well I just walked right over it, without having to think twice about it.

I guess I kinda like the e-lockers now....
