The ARB Air Locker Differential for Ford 10.25" and 10.5" Sterling rear axles allows drivers to move slower, safer, and with greater control while reducing drivetrain shock, vehicle damage, and environmental impact.

With the flip of a switch, the Air Locker instantly locks the differential, preventing internal gears from rotating independently. This forces both axle shafts to turn together, ensuring maximum traction in mud, rocks, snow, and extreme off-road conditions. When disengaged, the differential operates like a conventional open unit for smooth, predictable on-road performance.
