I just pulled out my Detroit Locker and got an ARB. The Detroit is great in anything but the pavement. Not clanking around turns, I just did not like it pulling my Blazer from side to side when you either stepped on the gas or let off it. Since I drive in the city, to me, I found this to be dangerous in traffic.
i had a detroit in the rear of my cammed ls1 6 speed camaro. it always pulled hard to the right if you would down shift and get on it hard under like 45, definitely scary the fist time. didnt know thats what was causing that until after i sold the car.
