1. Diff Case: Fully machined 1 piece nodular iron diff carrier case offers the rigidity of a 1 piece diff but twice the number of pinion gears to handle the torque.

2. Flange Cap Assembly: Fully machined nodular iron flange cap incorporates the stationary side of ARB’s proven and patented timed locking mechanism.

3. Splined Side Gear: The most "lockable" gear in the industry due to High grade nickel alloy steel, aerospace grade surface treatments, and ARB’s patented timed locking system.

4. Pinion Gear: Gear tooth geometry to yield structural advantages of up to 30% over commercially available high strength gears.

5. Clutch Gear: ARB’s 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 technology make for a high pressure running fit that can handle huge work loads.

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 climactic temperatures.

10. Return Springs: ARB Air Lockers use between 4 and 12 return springs to support the entire profile of the locking gear for a fast, positive, and independent disengagement when the air is exhausted.

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 anodized billet, sealed against moisture and dust to IP54, ARB’s heavy duty solenoid controls the air actuation. A low watt coil ensures extra long life and protection against hot environments. Please note - some technical features may differ between models.
