The ARB Air Locker for the GM 14-Bolt 10.5" Full Float axle features a two-piece, ultra-strong steel construction, ARBs patented timed locking system, and a steel reinforced bonded seal engineered to withstand extreme climates and over 20,000+ engagement cycles. With the flip of a switch, the Air Locker instantly locks both axle shafts together, ensuring maximum traction in the most extreme off-road conditions.

Unlike automatic lockers, the ARB Air Locker operates as a conventional open differential when disengaged, allowing smooth handling and reduced driveline wear during normal driving. When activated, its pneumatically operated locking mechanism prevents the internal differential gears from rotating independently, forcing both wheels to turn together and maintain traction regardless of terrain.

• ARB GM 14-Bolt 10.5" Air Locker Differential

Tech Insight

ARBs patented timed locking mechanism ensures ultra-fast engagement and disengagement while maintaining strength under extreme torque loads. The steel-reinforced, elastomer-bonded annular seal provides unmatched reliability in hot, cold, wet, and dusty environmentsmaking this locker a proven choice for rock crawling, racing, towing, and expedition builds.

Selectable locking allows drivers to maintain control, reduce vehicle stress, and minimize environmental impact compared to constant-locking differentials.
