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.
