Product Information

The world's premier traction aid, an ARB Air Locker keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact. ; | ARB Air Locker Differential Dana 60HD, 35 SPL, 4.56 & UP RD166 | Ford F-350 Super Duty (1999-2022) | Silver | Steel | Compatible with: Chevrolet C20 Pickup (1970-1974), Chevrolet C20 (1975-1986), Chevrolet C30 Pickup (1970-1974), Chevrolet C30 (1975-1986), Chevrolet K20 Pickup (1970-1974), Chevrolet K20 (1975-1986), Chevrolet K30 Pickup (1970-1974), Chevrolet K30 (1977-1986), Dodge D250 (1981-1993), Dodge D350 (1981-1993), Dodge Ram 2500 (1994-2003), Dodge Ram 3500 (1994-2003), Dodge W200 (1975-1980), Dodge W250 (1981-1993), Dodge W300 (1975-1980), Dodge W350 (1981-1993), Ford E-150 (2008-2013), Ford E-200 Econoline (1969-1974), Ford E-250 Econoline Club Wagon (1986-1991), Ford E-250 Econoline (1986-2002), Ford E-250 (2003-2014), Ford E-350 Club Wagon (2003-2005), Ford E-350 Econoline Club Wagon (1977-2002), Ford E-350 Econoline (1975-1998), Ford E-350 Super Duty (1999-2008), Ford E-450 Econoline Super Duty (2000-2002), Ford E-450 Super Duty (2003-2008), Ford F-250 HD (1997), Ford F-250 Super Duty (1999-2022), Ford F-250 (1976-1999), Ford F-350 Super Duty (1999-2022), Ford F-350 (1978-1997), Ford F-450 Super Duty (2000-2020), Ford F-550 Super Duty (2000-2004), GMC C25 (1975-1978), GMC C25/C2500 Pickup (1970-1974), GMC C35 (1975-1978), GMC C35/C3500 Pickup (1970-1974), GMC K25 (1975-1978), GMC K25/K2500 Pickup (1970-1974), GMC K35 (1977-1978), GMC K35/K3500 Pickup (1970-1974)
