OX Locker
I run an OX in the rear D44. I can't speak highly enough of this product. Easy install, very good directions, brutally strong and locks and unlocks on command every time. People who have trouble with them locking and unlocking have set the cable up wrong. Set the cable up with the diff cover on the bench not on the vehicle.
I don't have any first hand experience, but everyone I know that runs one likes it.

Toss-up for my future locking choice for my front/rear axles: I've heard great things about Ox lockers for durability and operation, similar to ARB locker reputation. And initially looking, the price is decent considering that the locker itself comes with the diff cover, too (which is integral to the locking system), but cables and levers (not including the electronic and/or air solenoid options) are about $200 extra. After the total package is taken into consideration, the Ox is practially the same cost as an ARB locker without the onboard air system. Any opinions?

Both are well engineered designs, but if you may have to deal with Canadian winter temperatures, I'd go for the Ox.
