ARB AIR LOCKERS
While your four-wheel-drive is designed to receive power (drive) to all four wheels, power can only be delivered to a maximum of two wheels at any one time without the assistance of a differential lock.

ARB offers one of the world’s most famous and proven locking differentials, the ARB Air Locker. Air Lockers are an Australian designed and manufactured selectable differential locker that can be activated at the flick of a switch at any speed.
