The ARB Air Locker for the GM 14 Bolt 10.5 axle is the world’s premier selectable locking differential, engineered for extreme off-road, racing, and high-performance applications. With the flip of a switch, the Air Locker delivers instant 100% traction on demand, allowing both axle shafts to rotate together for maximum control in the toughest terrain.

Designed for strength and reliability, this Air Locker uses ARB’s proven pneumatically actuated locking system, enabling engagement at any speed while maintaining normal open-differential behavior when unlocked. This allows for safer, smoother on-road driving while providing unmatched traction off-road.

Tech Insight

ARB Air Lockers use a two-piece design with minimal moving parts, ensuring maximum reliability under extreme torque loads. The patented timed locking mechanism delivers ultra-fast engagement and disengagement, while the steel-reinforced elastomer annular seal is proven to withstand 20,000+ activation cycles in the harshest climates on Earth.

Advanced internal components — including forged gears, a long cross shaft, and reinforced spider block — provide up to 30% greater strength over conventional high-strength differential gears.
