ARB Airlocker Dana44 30Spl 3.92&Up S/N. - RD116Find parts that fit my vehicle

The world's premier traction aid, an ARB Air Locker(TM) keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.

Your drivetrain is all the components responsible for transferring power from your engine and delivering it to the wheels. Drivetrain components are vital to your vehicles operation.

Side markers are a great safety device that helps other drivers indicate your location on the road. Sidemarkers can be life saving when it comes to driving on dark roads or in foggy weather.

The origins of ARB can be traced back to Australia's remote Top End, circa 1975. A region of vast distances and rugged terrain, it was fast becoming a Mecca for the nation's burgeoning 4WD community. However, the very environment that attracted 4 wheelers also wreaked havoc on their equipment - when driving in extreme conditions, only the best 4x4 accessories will do.

This was the conclusion drawn by Tony Brown during his travels at the time. While exploring the treasures of the Top End, the skills Tony gained from working on his Land Rover were regularly called on to mend damaged bull bars and broken roof racks. Bar work back then was crude, not at all suited to overland touring, and through this experience an idea was born - high quality equipment that met the vigorous demands of 4WD owners.

Upon returning to Melbourne, Tony put theory into practice via the family garage, where he sought to address the product deficiencies he'd encountered. His vision called for a combination of sound design principles and reliable raw materials... a simple solution to an endemic problem. The concept was embraced when it hit the fledgling 4x4 market, and ARB - the initials of Anthony Ronald Brown - was founded.

Today, ARB is Australia's largest manufacturer and distributor of 4x4 accessories. We also have an international presence, with an office in the US and an export network that extends through more than 80 countries around the globe. Our philosophy, however, has never wavered from its original course - quality, reliability and practicality above all else.
