# ARB Airlocker 31 Spl Ford 8.8In S/N The world's premier traction aid, an ARB Air Locker(TM) 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. - Easy, convenient operation allows the user to concentrate on the terrain without leaving the comfort and safety of the driver's seat - Steel reinforced, elastomer bonded annular seal designed to handle the most extreme climatic temperatures on Earth - Two-piece design is ultra-durable and extremely strong ? minimal moving parts ensure maximum reliability - Kit includes: Air Locker differential, activation switch, solenoid valve, air line and bulkhead fitting - Provides 100 percent traction on demand without affecting on-road drivability or driveline wear - Patented ?timed' locking mechanism offers high strength and ultra-fast unlocking - Employs Minimal Moving Parts Ensuring Maximum Reliability - Air compressor required for operation (sold separately) This Part Fits: Year Make Model Submodel 1990-1997 Ford Aerostar Base 1990-1994 Ford Aerostar Eddie Bauer 1990-1994 Ford Aerostar XL 1990-1994 Ford Aerostar XL Plus 1991-1994 Ford Aerostar XL Sport 1990-1997 Ford Aerostar XLT 1990-1997 Ford Aerostar XLT Plus 1991-1997 Ford Aerostar XLT Sport 1983-1993 Ford Bronco Custom 1985-1996 Ford Bronco Eddie Bauer 1990-1996 Ford Bronco XL 1983 Ford Bronco XLS 1984-1992,1994-1996 Ford Bronco XLT 1983,1993 Ford Bronco XLT Lariat 1992 Ford Bronco XLT Nite 1995-1996 Ford Bronco XLT Sport 1984-1986 Ford Bronco II Base 1984-1990 Ford Bronco II Eddie Bauer 1987-1990 Ford Bronco II XL 1988-1990 Ford Bronco II XL Sport 1984-1985 Ford Bronco II XLS 1984-1990 Ford Bronco II XLT 1989-1990 Ford Bronco II XLT Plus 2003-2008,2010-2011 Ford Crown Victoria Base 2006-2009 Ford Crown Victoria Fleet 2003-2009 Ford Crown Victoria LWB 2003-2011 Ford Crown Victoria LX 2004-2006 Ford Crown Victoria LX Sport 2003-2011 Ford Crown Victoria Police Interceptor 2003-2005 Ford Crown Victoria S 2005 Ford Crown Victoria Special Edition 1983 Ford E-100 Econoline Custom 1983 Ford E-100 Econoline XL 1983 Ford E-100 Econoline Club Wagon Custom 1983 Ford E-100 Econoline Club Wagon XL 2003-2014 Ford E-150 Base 2006-2007 Ford E-150 Chateau 2006-2014 Ford E-150 XL 2006-2014 Ford E-150 XLT 2003-2005 Ford E-150 Club Wagon Chateau 2003-2005 Ford E-150 Club Wagon XL 2003-2005 Ford E-150 Club Wagon XLT 1984-1986,1992-2002 Ford E-150 Econoline Base 1983,1987-1991 Ford E-150 Econoline Custom 1983-2000 Ford E-150 Econoline XL 1984-1986 Ford E-150 Econoline Club Wagon Base 1992-2002 Ford E-150 Econoline Club Wagon Chateau 1983,1987-2000 Ford E-150 Econoline Club Wagon Custom 1983-1991,2001-2002 Ford E-150 Econoline Club Wagon XL 1984-2002 Ford E-150 Econoline Club Wagon XLT 1984-1986,1992-1999 Ford E-250 Econoline Base 1983,1987-1991 Ford E-250 Econoline Custom 1983-1999 Ford E-250 Econoline XL 1984-1986 Ford E-250 Econoline Club Wagon Base 1983,1987-1991 Ford E-250 Econoline Club Wagon Custom 1983-1991 Ford E-250 Econoline Club Wagon XL 1984-1991 Ford E-250 Econoline Club Wagon XLT 1997-2001 Ford Expedition Eddie Bauer 1997-2001 Ford Expedition XLT 2011-2014 Ford Explorer Base 1991-2010 Ford Explorer Eddie Bauer 1995 Ford Explorer Expedition 1993-2014 Ford Explorer Limited 2004 Ford Explorer NBX 2000-2003 Ford Explorer Postal 1991-2000,2013-2014 Ford Explorer Sport 1991-1999 Ford Explorer XL 2000-2001 Ford Explorer XL Fleet 1999-2006 Ford Explorer XLS 2004-2005 Ford Explorer XLS Sport 1991-2014 Ford Explorer XLT 2004-2005 Ford Explorer XLT Sport 2001-2002 Ford Explorer Sport Base 2003 Ford Explorer Sport XLS 2003 Ford Explorer Sport XLT 2005 Ford Explorer Sport Trac Adrenalin 2001 Ford Explorer Sport Trac Base 2007-2010 Ford Explorer Sport Trac Limited 2002 Ford Explorer Sport Trac XL 2003-2005 Ford Explorer Sport Trac XLS 2003-2005,2007-2010 Ford Explorer Sport Trac XLT 1983-1986,1997-2000 Ford F-150 Base 1987-1992 Ford F-150 Custom 1995-1996 Ford F-150 Eddie Bauer 2000-2003 Ford F-150 Harley-Davidson Edition 2001-2003 Ford F-150 King Ranch 1997-2003 Ford F-150 Lariat 1993-1995,1999-2003 Ford F-150 Lightning 1995-1996 Ford F-150 Special 1983-2003 Ford F-150 XL 1983 Ford F-150 XLS 1983-1984,1993-2003 Ford F-150 XLT 1985-1992 Ford F-150 XLT Lariat 2004 Ford F-150 Heritage SVT Lightning 2004 Ford F-150 Heritage XL 2004 Ford F-150 Heritage XLT 1997-1999 Ford F-250 Base 1997-1999 Ford F-250 Lariat 1997-1999 Ford F-250 XL 1997-1999 Ford F-250 XLT 2009-2010 Ford F-250 Super Duty Cabela's 2008-2009 Ford F-250 Super Duty FX4 2004-2010 Ford F-250 Super Duty Harley-Davidson Edition 2004-2019 Ford F-250 Super Duty King Ranch 1999-2019 Ford F-250 Super Duty Lariat 2018-2019 Ford F-250 Super Duty Limited 2013-2019 Ford F-250 Super Duty Platinum 1999-2019 Ford F-250 Super Duty XL 1999-2019 Ford F-250 Super Duty XLT 1990-1992 Ford Ranger Custom 2001-2005 Ford Ranger Edge 1998-2002 Ford Ranger EV 2005-2009 Ford Ranger FX4 2002 Ford Ranger Postal 1990-1992 Ford Ranger S 1990 Ford Ranger S Plus 1993-1998 Ford Ranger Splash 1991-1993,1997,2006-2011 Ford Ranger Sport 1990-1997,2005-2007 Ford Ranger STX 2004 Ford Ranger Tremor 1993-2011 Ford Ranger XL 1995 Ford Ranger XL Sport 1990-2011 Ford Ranger XLT 1994 Mazda B4000 LE 1994 Mazda B4000 SE 1992-1994 Mazda Navajo DX 1991-1994 Mazda Navajo LX ## Details -
