New ARB Air Lockers
Over the last few months ARB’s team of Air Locker
engineers has been hard at work developing new
product to further expand the already large range
available.
An ARB Air Locker is a driver controlled replacement
locking differential that essentially ‘locks’ the two front
or two rear wheels so they don’t turn independently.
When a standard vehicle experiences a loss of
traction, power is automatically sent to the path of least
resistance (usually the wheel with little or no traction),
resulting in no forward movement. However, when an

This JK rubicon didn't want to disengage the front locker on the trail. We removed and dissassembled the factory electric locker and found heavy wear patterns in the holes the actuator tabs go through. This vehicle had about 10k miles on it. The locker is not serviceable in any way short of replacement, so we had to install a whole new locker.

It is a common misconception that 4x4 and traction go hand in hand. The truth is that most 4x4 vehicles send power to the wheels with the least amount of traction once difficult terrain is encountered. The problem is simple – when one of your vehicle’s wheels loses traction, your highway minded factory differential directs all of your vehicle’s power to those spinning wheels. On road, the standard differential allows each of your wheels to turn independently thus eliminating any binding during turns.
