Four wheel driving can be frustrating. You know
you have the vehicle to take on the most extreme
terrains, yet you find that it baulks at the slightest
of obstacles, quite often losing traction at the most
inappropriate times, leaving you stranded &
embarrassed.
Air Locker is the answer.

| Advantages of an ARB Air Locker! |
Easy to Use:
Dash-mounted push-button operation allows the driver to engage or disengage the Air Locker at will; locking takes place in 1/10th of a second.
|
Reliable:
Uses high-grade aircraft alloy components; up to twice as strong as stock differential components.
|
Versatile:
Ideal for both street and trail use; especially suited for use in front differentials.
|
Air Powered:
On-board air compressor provides 80-105 psi for inflating tires, rafts, etc; fast-recovery compressor. When using Optional Inflation kit.

Many types of traction devices have been available for years, but until the ARB Air Locking Differential, all were a compromise, performing well either off the road or on the road, but not on both. The Air Locking Differential provides normal differential action on the highway, maintaining safe, predictable handling. Once off the road, by simply pushing the buttons, the Air Locking Differentials lock the axles together providing 100% traction to all wheels allowing you to safely traverse even the most difficult terrain.
Without diff locks, when one wheel loses traction, all the driving torque transfers to that wheel leaving it spinning helplessly. With the ARB Air Locking differential activated you will simply drive out of these situations. The ARB Air Locker is an air operated, driver controlled differential lock activated by pushing a dash mounted button. When the dash mounted button is pushed, compressed air, delivered by the ARB 12 volt, on board air compressor is passed via a 12 volt solenoid down an air line into the differential housing. The air travels into the differential centre via a specially designed seal housing which seals against an extended bearing spigot.
Via air galleries, the compressed air enters the piston chamber and actuates the piston and clutch gear, moving the gear into the locked position. The clutch gear now locks the side gear to the differential housing instantly stopping any differential action. The diff is now 100% locked, and both axles will deliver 100% traction.
|
| To disengage the differential the dash mounted switch is again pushed, which releases the compressed air via the solenoid and the piston springs return the piston to its original position. The differential is then fully open allowing full, standard differential action. The ARB Air Locker only takes a split second to engage, making it the only, truly, driver controlled, differential locking system. |
