The ARB Air Locking diffs have been the pioneer and premier option in diff locks for years.
Their strength and durability makes them the obvious choice for someone wanting to take their vehicle to the next level. Don’t be confused these are not only for competition work, they will turn your recreational 4WD into a true 4WD.
Check out the video for a full run down on what makes the ARB Air Locker the best in the market.
The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the 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 crown wheel, the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like a conventional ‘open’ differential.
In addition to providing outright improvements to a 4×4’s off road capabilities, the Air Locker offers significant environmental benefits. An Air Locker equipped truck can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.
