I've had it for about 3 weeks now!are you in the process of purchasing an FJ? Either way if you do not have ATRAC you can add the switch for around 50 bucks. The locking diff option gives you the ability to have it so all it takes is the switch. Hope this helps.
you WANT Atrac!! :bigthumb:Any rear differential with a locking mechanism is pre-wired for Atrac. Read more about installing it here. It's as simple as installing a light bulb (almost).... on my MT-6.
Do I also have/need ATRAC?
