ARB

ARB Air Lockers are the selectable locker that can turn your open differential into a locked spool at the flick of a switch. When traction is mandatory without the sacrifice of street drivability, the ARB Air Locker is the answer. Most people think 4WD (or 4×4) means that all four tires drive the vehicle. This isn’t exactly the case and the truth about 4WD is often discovered when the vehicle encounters difficult terrain because the tires with the least amount of traction are the ones receiving all of the power. This is where the ARB Air Locker serves its purpose. At the flick of a switch, compressed air locks the internal components to provide 100% traction to both tires on demand and when full traction is not required, the air locker will unlock just as quickly restoring the axle’s open differential street driving characteristics.
