When activated, it delivers equal drive to both wheels on an axle, allowing you to take full advantage of the available traction in all conditions. Specifically designed for the Toyota 8 Inch rear axle featuring a side adjuster housing and a 10 bolt ring gear, this 30 spline Air Locker ensures reliable performance for your 4x4. 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 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 Toyota 8 Inch equipped vehicle.
When disengaged, the Air Locker functions just like an open differential, maintaining safe and predictable handling on sealed surfaces.
