If you don't need it now - you probably won't regret it. I would put one in for my own use. But - the ATRAC really is pretty good. For most people it's more than enough. I would not put a limited slip in. ATRAC is already better than any limited slip I know of. So it would just be throwing your money away.



The situation where a locker helps most are where there is a big difference between static and kinetic friction. Meaning once the tire spins you lose a lot of traction. Snow and ice is the most significant gap between the two traction types. So lockers are more beneficial as compared to traction control on snow and ice than any other surface condition. The next would probably be something like loose rocks/dirt. On the other end of the spectrum is high traction surfaces like slickrock in Utah. They are probably least beneficial on that type of rocks. Other conditions are somewhere in between.

I would rather have a winch than a rear locker since you already have ATRAC. If you didn't have ATRAC - yeah, front and rear lockers would be the first place i'd spend my $. But since you already have ATRAC and it's pretty damn good. Winch would be where I'd spend my $. If you don't have one. I use my rear locker a lot more. But I could get by without it. When I need the winch - I NEED the winch. There's really no alternative that offers as much bang for the buck in terms of overall utility for me as a winch when you're stuck.
