    I just finished reading post about running Detroit Lockers on pavement......and learned alot.
    Now, can someone give me a brief idea of how an ARB locker works? I sortof know, but am not real clear, also, how do they perform on the pavement, and how they stack up against the Detroit system?
    Thanks!

    a arb is air activated if you push the switch it pumpes air in and forces the clutches to engage and locks the dif when you push the switch again it lets the air out and you then have an open dif

    better than a detroit locker offroad and same as a open diff(spider gear). Best of both worlds at a price I wish my wife would let me afford $650-$700. read more about it at <a target="_blank" href=http://www.arbusa.com/>http://www.arbusa.com/</a>

    If you could afford it, the ideal would probably be ARB in both the front and the rear. However, at $700+ per locker plus the cost of the compressor, that is not usually practical. In addition, there are more moving parts in these lockers and the issue of compressed air, tubes, and o-rings. These all contribute to the possibility of more points of failure.

    I have Detroits in front and rear. I am pleased with them. I control whether or not my front one is "on" or not by simply switching in and out of 4WD.

    On my trail rig, I plan to have a Detroit in the rear 14BFF and an ARB in the front D60. But, when pricing one, don't forget to include the cost of the compressor. They don't include that in the adds when they say that the ARB locker setup is only $649 or whatever.

    You can run an ARB without the compressor! If you have a Power Tank or other homemade air tank system, you can simply run the ARB off of that! The compressor makes it easy and you never have to worry about running out of air for the locker, but you CAN run it without the compressor. I have an ARB up front, Detroit in rear - I love having the ARB up front and I will never run anything else in the front axle!!
