I kinda disagree on the Atrac not keeping you from getting stuck, I’ve grown to really like it, when used properly it’s pretty awesome, I’m mainly talking about use on rocks , ruts etc. but moderate stuff , I come from a old school rock crawling background where low gears and lockers were the key, I always scoffed at traction control on rigs, until I actually had it. but the ATRAC has proven its self time and again when climbing small ledges or similar situations.I have a Lokka locker on my 80 and I really like it. Other than the auto locker ratcheting around corners, you would have no idea it was there. I have ATRAC in my LX470, and I think it may help you get out of trouble, it does next to nothing to keep you from getting into it to begin with. ATRAC works once you are stuck, and the other thing I am not a fan of is that you have to keep the RPMs up ~2500+ when it is doing its thing. I would say it does work, but it is not a proactive system. I ended up putting a locked axle from a '99 into my 2000 LX, so when you know you are going to need it, you can have it. I think an auto locker provides that same service. I made the switch mostly due to my axle seals and bearings going out, but I would have added an auto locker without any hesitation.
