Description

A relentless commitment to research and design, the use of quality materials, and an uncompromising approach to manufacturing have all contributed to the Air Locker’s success in over 100 countries worldwide.

Designed and manufactured in Australia, ARB Air Lockers will enhance the traction of your 4×4 in just about any terrain, whether it’s rock, clay, gravel, sand, snow or mud.

Now with a state-of-the-art two piece design available right across the range, forged gears for the ultimate in strength and durability, and an industry-leading five year warranty, ARB Air Lockers are better built and better backed than ever before.

Features

  • Air Supply: At the flick of a dash-mounted switch, compressed air is delivered to the seal housing assembly via a nylon air line.
  • Diff Case: Fully machined, one-piece nodular iron diff carrier case offers the rigidy of a one-piece factory differential with twice the standard number of pinion gears to cope with the torque.
  • 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.
  • Long Cross Shaft: Alloy steels and performance surface technology make for a high pressure running fit that can handle an enormous amount of punishment.
  • 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.
  • 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.
  • 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 commercial, race and agricultural transmissions.
  • 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.
  • 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.
  • Clutch Gear: ARB’s patented locking system actually supports the side gear teeth, giving you more torque handling capability, exactly when you need it.
  • Cross Shaft Retaining Pin: Custom made, one-piece hardened retaining pins lock into the assembly using a tapered thread junction.
  • Flange Cap Assembly: Fully machined nodular iron flange cap incorporates the stationary side of ARB’s tough, proven and patented timed locking mechanism.
