The ARB Air Locker for Ford 9-inch axles features a 31-spline shaft configuration and fits 9-inch ring gear differentials to deliver on-demand traction. Its pneumatic locking system ties both wheels to the ring gear when activated, improving off-road capability without compromising normal on-road drivability. The kit includes the locker, switch, solenoid valve, air line and bulkhead fitting; an air compressor is required and sold separately.
