ARB Air Locker
The ARB Air Locker is designed to get rid of that spinning tire that does nothing on the trail but get you stuck. By installing a locker in your vehicle, you guarantee that you’ll have full traction if you have a tire dangling in the air, are in the deepest mud, slickest snow, or gnarliest rock pile. It essentially ‘locks’ your differential.
The ARB air locker takes it one step further by allowing you to turn your locker on, and turn it off. No funky handling characteristics on the highway as with other lockers.
ARB lockers put YOU in control!
Driver controlled, push button actuation for 100% instant traction.
Up to 100% stronger than the stock differential in most cases.
Designed and manufactured in Australia for the demanding rigors of the ‘outback’ for over 10 years.
The air locker is silent in operation unlike most automatic type locking differentials. Unlocked, it offers the same superior smooth handling and cornering as your factory ‘open’ differentials.
When engaged, the air locker will not allow one wheel on a drive axle to spin hopelessly whilst the other wheel remains motionless.
Designed, tested, and manufactured to be stronger than your axle components so breakage is not an issue.
Installation assistance available directly from ARB’s tech staff.
ARB’s reputation for warranty and assistance is second to none in the aftermarket parts industry.
Full power is transmitted to both wheels in all situations when the locker is engaged.

A common misconception suggests that a 4×4 and traction go hand in hand… you can’t have one without the other. The truth, however, is that most 4×4 vehicles send power to the wheels with the least amount of traction once difficult terrain is encountered. The problem is simple – when one (or more) 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 “open” differential allows each of your wheels to turn independently thus eliminating any binding during turns. Off road, this becomes a major burden as engine power will take the path of least resistance, which occurs at the wheels with little or no traction.
Newer vehicles with limited slip differentials (LSDs), positraction etc may offer some improvement over standard differentials, but more often you’ll find the slipping is not “limited” enough to maintain forward progress. Automatic locking differentials also have their disadvantages. Aside from being noisy, automatic locking differentials often upset the on highway and off road driving characteristics of your 4×4. During normal driving conditions, vehicle responsiveness becomes less predictable, and when highway surfaces become wet or icy, the driver must use extreme caution just to keep the truck in control.
ARB has been challenging conventional thinking on off road equipment designs for over 30 years, and the ARB Air Locker has been a success from the very beginning. Created to provide 100% traction on demand, without sacrificing any of your vehicle’s highway driving performance, ARB Air Lockers employ a 12 volt air compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flick of a switch, all within the safety and comfort of the driver’s seat.

the ARB locker and its superiority on the trail and road.
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 ring gear the vehicle maintains maximum possible traction at all times. When unlocked, it operates just like conventional “open” differentials.
In addition to providing outright improvements to a 4×4’s off road capabilities, the Air Locker offers significant environmental benefits.When approaching difficult terrain, less reliance is put on momentum.An Air Locker equipped truck can be driven in a slower, safer and more controlled manner as a result of vastly improved traction. This style of driving greatly reduces the likelihood of incurring vehicle damage and lessens the environmental impact as well.
