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 4x4 and traction go hand in hand… you can’t have one without the other. The truth, however, is that most 4x4 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 4x4. 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 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 4x4’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.

The RDCKA compressor from ARB
CKSA12 model Compact compressor
These great compact compressor kits are what you need if you plan on installing ARB lockers.
The RDCKA has other useful benefits besides just operating your air lockers. It can also be used as an air supply on the trail to fill up tires, help reseat beads, any number of air related problems.
The vehicle mounted CKSA12 was built exclusively to activate Air Locker locking differentials. This is a very compact compressor which will allows fitment into vehicles with very little space.
The new ARB - CKMTA12: This compact vehicle mounted compressor has been designed to do everything! Activate your ARB Air Locking Differentials, air up a 35" tire in less than a minute and run air tools. This 100% duty cycle, 6.16 CFM compressor is built to support all of your compressed air needs.
All ARB compressors comes with complete wire harness, switch, fittings, pressure switch, and built-in air tank.
Kit contains a heavy duty hose and locking chuck that easily bolton to the ARB compressor. The ARB Pump-up kit can be used even with front and rear air lockers. Use it to air up at the end of the trail, assist with repairs or flats, even to pump up your air mattress, inflatable raft, bicycle tires, anything that uses air for inflation. Typical ARB super high quality components make up this system. This is a must have item if you have an ARB compressor and a super simple add-on!
The ARB Air lockers do come with factory plastic blue line. While functional many people want something substantially beefier. This optional kit uses super beefy stainless air lines for your air locker. Eliminates the possibility of air lines kinking or breaking due to trail snafus. We've had our factory ARB air line kink on the trail. You'll do a double take when you see how strong these stainless braided lines are. Comes with metric fitting ready to plug into your ARB system. For most short and medium wheelbase 4WD vehicles, a 7' front and 13' rear are the perfect combination. For pickups, Suburbans, other long wheelbase vehicles, a 17' rear air line is recommended.
This Air Line Repair Kit is a must for vehicles that utilize air locking differentials and for those who have not upgraded to our stainless steel air lines. The stock blue hose is cut, nicked, burned, torn, or damaged easily enough and you lose your locker when this happen.
