Features
Differential Case
Fully machined one piece nodular iron differential carrier case offers the rigidity of a one piece factory differential with twice the standard number of pinion gears to cope with the torque.
Flange Cap Assembly
Fully machined nodular iron flange cap incorporates the stationary side of ARB’s tough, proven and patented timed locking mechanism.
Splined Side Gear
High grade surface treatments, nickel alloy steel and ARB’s patented timed locking system make this the most "lockable" gear in the industry.
Pinion Gear
Forged gears and redefined tooth geometry, ARB's revolutionary design yields structural advantages of up to 30% over other available high strength gears.
Clutch Gear
ARB’s patented locking system actually supports the side gear teeth, giving you more torque handling exactly when you need it.
Spider Block
A billet machined alloy steel spider block supports the cross shafts, using the torque applied at each shaft to support the next shaft along.
Long Cross Shaft
Alloy steels and performance surface technology make for a high pressure running fit that can handle an enormous amount of punishment.
Cross Shaft Retaining Pin
Custom made one piece hardened retaining pins lock into the assembly using a tapered thread junction.
Bonded Seal
Steel reinforced, elastomer bonded annular seal has been proven to handle 20,000+ cycles under the most extreme climactic temperatures on earth.
Return Springs
To engage/disengage the locker, ARB Air Lockers use up to 12 return springs to support the entire profile of the locking gear for a fast, positive and independent.
Air Supply
At the flick of a dash mounted switch, compressed air is delivered to a seal housing assembly via a nylon air line.
Solenoid Valve
Manufactured from a machined and anodized billet aluminum and sealed against moisture and dust to IP54 standards, ARB's heavy duty solenoid controls the air actuation.
Product Details
Air Locker™ Differential by ARB®. Created to provide 100% traction on demand, without sacrificing any of your vehicle's highway driving performance, ARB Air Lockers employ a 12 volt ARB 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 flip of a switch and all within the comfort of the driver's seat.
Installation
Many people believe that a 4x4 and traction go hand in hand...you can't have one without the other. However, your vehicle's standard (or open) differential is designed to allow each wheel to turn independently, thus eliminating binding during turns. While 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 may offer some improvement, but more often you'll find the slipping not 'limited' enough to maintain forward progress. Automatic locking differentials also have their disadvantages. Aside from being noisy when disengaging, they can also upset the on-highway driving characteristics of your vehicle.
Created to provide 100% traction on demand, without sacrificing any of your vehicle's highway driving performance, ARB Air Lockers employ a 12 volt ARB 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 flip of a switch and all within the 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 a conventional 'open' differential.
In addition to providing outright improvements to a 4x4's off road capabilities, the Air Locker offers significant environmental benefits. 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.
ARB Air Lockers are currently available in over 100 configurations to suit a wide range of 4x4 vehicles from around the world and can be installed in both the front and rear axles. Installation should be performed by a qualified differential technician, although no special tools or skills are required apart from those necessary for fitting a standard differential. ARB also offers three compressor models suitable for Air Locker operation, two of which can be used to inflate tires and other equipment such as air tools.
