When disengaged, the differential functions as a conventional open differential, allowing for smooth on-road driving and minimizing driveline wear. The ARB Air Locker's design enables activation at any speed, giving you control over traction without compromising vehicle handling or safety. Its compatibility with AAM 11.5-inch rear axles, 1.56-inch shafts, and 30-spline configurations makes it a versatile upgrade for serious off-road enthusiasts and commercial users alike. The unit's silver finish adds a professional look while resisting corrosion and environmental elements.
