ARB's World Renowned
Air Locker Locking Differential.

HOW THE AIR LOCKER WORKS

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 center 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.

All Bumpers shipped truck freight. Shipping is free within the continental United States on items with a delivered price.
