In the unlocked mode the locking differential acts as a normal differential, which could be either an open or a limited slip differential.
In locked mode the left and right axle shafts are coupled together, providing maximum traction with the ground
100% of input torque can be applied to both wheels
Typically used at low vehicle speeds when maximum traction is required
Primarily applicable to rear axles
In unlocked mode is compatible with ABS, traction and stability control systems. When in locked mode will not allow left to right speed difference, so reduced performance of these systems may be expected.
