ARB Air Lockers & Accessories


1. 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.

2. FLANGE CAP ASSEMBLY

Fully machined nodular iron flange cap incorporates the stationary side of ARBís tough, proven and patented timed locking mechanism.

3. SPLINED SIDE GEAR

High grade surface treatments, nickel alloy steel and ARBís patented timed locking system make this the most Ďlockableí gear in the industry.

4. PINION GEAR

ARB has redefined differential gear tooth geometry to yield structural advantages of up to 30% over commercially available high strength gears.

5. CLUTCH GEAR

ARBís patented locking system actually supports the side gear teeth, giving you more torque handling exactly when you need it.

6. 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.

7. LONG CROSS SHAFT

Alloy steels and performance surface technology make for a high pressure running fit that can handle an enormous amount of punishment.

8. CROSS SHAFT RETAINING PIN

Custom made one piece hardened retaining pins lock into the assembly using a tapered thread junction.

9. BONDED SEAL

Steel reinforced, elastomer bonded annular seal has been proven to handle 20,000+ cycles under the most extreme climatic temperatures on earth.

10. 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.

11. AIR SUPPLY

At the flick of a dash mounted switch, compressed air is delivered to a seal housing assembly via a nylon air line.

12. SOLENOID VALVE

Manufactured from a machined and anodised billet, and sealed against moisture and dust to IP54 standards, ARBís heavy duty solenoid controls the air actuation.
