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 70/80, 32 SPL, LOW SPEED RD173 | Ford F-350 Super Duty (1999-2016) | Silver | Steel | Compatible with: Chevrolet C30 (1976-1986), Chevrolet C3500 (1988-2000), Chevrolet C3500HD (1991-2001), Chevrolet G30 (1996), Chevrolet K30 Pickup (1970-1974), Chevrolet K30 (1977-1986), Chevrolet K3500 (1990-1998), Dodge B300 Van (1971-1974), Dodge B300 (1975-1980), Dodge B350 (1981-1994), Dodge B3500 (1995-1998), Dodge D250 (1981-1993), Dodge D300 Pickup (1970-1974), Dodge D300 (1975-1980), Dodge D350 (1981-1993), Dodge Ram 2500 (1994-2003), Dodge Ram 3500 (1994-2003), Dodge W200 Pickup (1970-1974), Dodge W200 (1975), Dodge W250 (1981-1984), Dodge W300 Pickup (1970-1974), Dodge W300 (1975-1978), Dodge W350 (1981-1993), 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 (1999-2010), Ford E-450 Econoline Super Duty (1999-2002), Ford E-450 Super Duty (2003-2010), Ford F-350 Super Duty (1999-2016), Ford F-350 (1970-1997), GMC C35 (1975-1978), GMC C35/C3500 Pickup (1974), GMC C3500 (1988-2000), GMC C3500HD (1991-2001), GMC K35 (1977-1978), GMC K3500 (1988-2000)
