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 Ford 10.25" & 10.5" RD140 | Ford F-350 Super Duty (1999-2016) | Silver | Steel | Compatible with: Ford E-150 Club Wagon (2003-2005), Ford E-150 Econoline Club Wagon (2000-2002), Ford E-150 Econoline (2000-2002), Ford E-150 (2003-2010), Ford E-250 Econoline Club Wagon (1980-1991), Ford E-250 Econoline (1980-2002), Ford E-250 (2003-2014), Ford E-350 Club Wagon (2003-2005), Ford E-350 Econoline Club Wagon (1985-2002), Ford E-350 Econoline (1985-1998), Ford E-350 Super Duty (1999-2015), Ford E-450 Econoline Super Duty (2000-2002), Ford E-450 Super Duty (2003-2010), Ford E-550 Econoline Super Duty (2002), Ford E-550 Super Duty (2003), Ford Excursion (2000-2005), Ford F-250 HD (1997), Ford F-250 Super Duty (1999-2016), Ford F-250 (1985-1999), Ford F-350 Super Duty (1999-2016), Ford F-350 (1985-1997)
