ARB Air Lockers are selectable locking differentials that provide maximum traction when activated and normal open differential behavior when disengaged. This allows drivers to maintain factory-like handling on-road while enabling additional traction off-road for uneven or low-grip terrain.
Air Lockers are widely used in off-road recreation, overland travel, expedition builds, and towing applications where controlled traction and predictable power delivery are preferred over momentum-based driving.

ARB AIR LOCKERS
Tackling Technical Terrain
Selectable Traction When It Matters
On technical terrain, standard open differentials can limit progress when a wheel lifts or loses grip. When engaged, an Air Locker mechanically locks both axle shafts together, ensuring equal power delivery to both wheels and improving vehicle control at low speed.
- Reduces wheelspin
- Helps manage drivetrain stress
- Move through obstacles without aggressive throttle input
FAST, CONSISTENT ENGAGEMENT
Engineered for Reliability and Integration
Air Lockers use pneumatic actuation for fast, consistent engagement and are engineered to handle high torque loads, heat cycles, and repeated operation in off-road environments. Extensive testing and premium materials support long-term reliability, making Air Lockers a trusted traction upgrade worldwide.
FRONT & REAR CONFIGURATIONS
Front and Rear Applications
Air Lockers are available for front and rear axle configurations and can be controlled independently to match vehicle setup and terrain demands. This flexibility allows drivers to optimize traction while maintaining predictable steering behavior.
RESOURCES
Locker Setup Planning and Selection
Selecting the right locker configuration depends on vehicle usage, axle type, terrain, and overall build goals. ARB provides resources to assist with locker selection, including application guides and technical fitment support for popular axle platforms used in Toyota, Jeep, Ford, and GM 4x4 vehicles.
