Another vote for ARB. My Tacoma and my 4Runner are both locked front and rear with ARBs. Both are also running manual hubs. Both get daily driven.

The ARB is great with IFS because you can choose when to turn it on and off. Use it for an obstacle then turn it back off. If you feel something binding, turn it off. If you need to turn in a tight spot to reposition, turn it off. Obviously they're great on the street because it's like they aren't there. My sister's TJ has a Detroit in the rear and you can feel it kicking in all the time on the street. It's very annoying.

If you can't swing the selectable locker, my next vote would be the Detroit Truetrac. Should give minimal input on the street and help on trails. You can drag the brakes to trick it into locking up if you need extra help on an obstacle.
