Dodge axle runs the front ds all the time so it becomes an issue with big lifts. That's the problem with baby max, would throw the front ds all the time cause the angle was too steep.
But you can also buy free spin hubs for the aam axle.
But they also have issues with the super duty axle on Ravi's silver truck breaking ds everytime he uses it hard in 4x4, moral of the story here is don't make it retarded tall, and either axle will work fine
