Description

The ARB 6178111SP Air Locker Differential provides 100% on-demand traction for Toyota vehicles. It functions as a conventional open differential when unlocked and prevents internal differential gears from rotating when activated, ensuring both axle shafts turn at the same speed. An air compressor is required (sold separately).
