ARB AIR LOCKERS

Those who enjoy heading off the beaten track in their 4+—4 know that even the most familiar tracks can present you with unexpected conditions. Whether you’re up against a steep incline, uneven & rocky terrain or a slippery muddy track, being able to take advantage of traction is one of the most important elements.

In a vehicle with open differentials in 4WD mode, drive can only go to two wheels at any given time. At the flick of a switch, an ARB Air Locker can send equal drive to both wheels on an axle allowing you to take advantage of the wheels that have traction and push forward along the track.

All models include a 2-piece nodular steel housing for rigidity and exacting tolerances, housing four forged and hardened spider gears to handle extreme axle loads. ARB’s patented ?€?timed gear’ design and high-temperature resistant seals ensure responsive activation under the most extreme climatic conditions on earth.

DIFF CASE
Fully machined, one-piece nodular iron diff carrier case offers the rigidity of a one-piece factory differential with twice the standard number of pinion gears to cope with the torque. Fully machined nodular iron flange cap incorporates the stationary side of ARB’s tough, proven and patented timed locking mechanism.
RETURN SPRING
Instead of a complex external actuator system to engage/disengage the lock, ARB Air Lockers use up to 12 return springs to support the entire profile of the locking gear for a fast, positive and independent disengagement.
SPLINED SIDE GEAR
High grade surface treatments, forged nickel alloy steel and ARB’s patented timed locking system make this the most ?€?lockable’ gear in the industry.FORGED GEARS
AIR SUPPLY
At the flick of a dash-mounted switch, compressed air is delivered to the seal housing assembly via a nylon air line.
TWO PIECE DESIGN
Machining a case from two pieces instead of three results in a much higher dimensional accuracy of the finished assembly and has allowed ARB engineers to improve the design of other elements, resulting in a reduction of moving parts, increased strength and a more responsive activation.
BONDED SEAL
Steel reinforced, elastomer-bonded annular seal has been proven to handle 20,000+ cycles under the most extreme climatic temperatures on earth.
PINION GEAR
Combining the strength of forged nickel alloy steel with redefined gear-tooth geometry, ARB has revolutionised locking differential gear design to yield structural advantages of up to 30% over commercially available high strength gears.
CLUTCH GEAR
ARB’s patented locking system actually supports the side gear teeth, giving you more torque handling capability, exactly when you need it.
FORGED GEARS
With phenomenal forces being applied to the side and pinion gears within the differential, ARB has invested heavily in the application of forged gears, typically found in heavy duty ommercial, race and agricultural transmissions
