ARB Airlocker 31 Spl Ford 9In S/N - RD119

The world's premier traction aid, an ARB Air Locker keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.

The ARB Air Locker 31 Spline for Ford 9 inch rear axles is a driver-controlled, selectable locking differential engineered to provide ultimate traction on demand without sacrificing on-road driveability. When activated, it delivers equal drive to both wheels on your Ford 9 inch rear axle, allowing you to take full advantage of the available traction in all conditions.

A standard 'open' differential is a compromise, designed to allow wheels to turn at different speeds on pavement. off road, this becomes a liability, as it directs all power to the wheel with the least grip, leaving you stranded. While a limited-slip differential (LSD) offers a partial improvement, it requires wheelspin to engage and never truly locks. The ARB Air Locker overcomes this by solidly locking the 31 spline Ford 9 inch rear axle at the flick of a switch, providing 100% traction instantly.

This allows you to confidently tackle steep inclines, rocky obstacles, and slippery tracks with your rig equipped with a Ford 9 inch rear axle. When disengaged, the Air Locker functions just like an open differential, maintaining safe and predictable handling on sealed surfaces.
