The ARB is plenty strong. In fact I just read an article in one of the Off Road rags, where ARB had stated that a good percentage of their failure was due to bent axles ,in particular on the D35.
In general the ARB and the Detroit are going to be stronger than the Powertrax, or an EZ locker because they incorporate a new stronger carrier, rather than replacing existing side and spider gears in the stock carrier.
I really like the ARB in the front axle, because I can run it open most of the time but its there if I need it.

If at first you dont succeed, your replacement will try and try again.
