The ARB Air Locker is the worlds premier selectable traction aid, allowing vehicles to be driven slower, safer, and with greater control over obstacles. Designed for the Toyota 8" IFS clamshell front differential, this Air Locker allows you to instantly lock both axle shafts together at the flip of a switch.

Unlike automatic lockers, the ARB Air Locker operates as a fully open differential when disengaged, maintaining factory-like street manners and driveline longevity. When activated, compressed air engages a pneumatically operated locking system that prevents the internal differential gears from rotating independently, giving you true 100% traction on demand.

• ARB Toyota 8" IFSAir Locker Differential Assembly
