# ARB Airlocker 28 Spl Gm8.5In 10Bolt Aam860 S/N *Does NOT Dropship* 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 1994-1999,2005 Chevrolet Blazer Base 1992-1993 Chevrolet Blazer Cheyenne 1987 Chevrolet Blazer Custom Deluxe 1996-2004 Chevrolet Blazer LS 1995-2001 Chevrolet Blazer LT 1989-1991 Chevrolet Blazer Scottsdale 1987,1989-1994 Chevrolet Blazer Silverado 1994 Chevrolet Blazer Silverado Sport 1999-2001 Chevrolet Blazer Trailblazer 2001-2005 Chevrolet Blazer Xtreme 2003-2005 Chevrolet Blazer ZR2 2015 Chevrolet Colorado Base 2006-2008 Chevrolet Colorado LS 2006-2012,2015 Chevrolet Colorado LT 2006-2012,2015 Chevrolet Colorado WT 2015 Chevrolet Colorado Z71 1983 Chevrolet G10 Base 1982-1987 Chevrolet G10 Beauville 1982-1984,1986-1987 Chevrolet G10 Bonaventure 1982-1987 Chevrolet G10 Chevy Van 1982-1987 Chevrolet G10 Sportvan 1977-1981 Chevrolet K10 Cheyenne 1981-1986 Chevrolet K10 Custom 1977-1980 Chevrolet K10 Custom Deluxe 1981 Chevrolet K10 Deluxe 1977-1986 Chevrolet K10 Scottsdale 1977-1986 Chevrolet K10 Silverado 1981-1986 Chevrolet K10 Suburban Custom 1977-1980 Chevrolet K10 Suburban Custom Deluxe 1981 Chevrolet K10 Suburban Deluxe 1977-1980,1982,1984-1986 Chevrolet K10 Suburban Scottsdale 1977,1979-1980,1982-1983,1985-1986 Chevrolet K10 Suburban Silverado 1994-1997 Chevrolet K1500 Base 1988-1998 Chevrolet K1500 Cheyenne 1999 Chevrolet K1500 LS 1988-1992 Chevrolet K1500 Scottsdale 1988-1998 Chevrolet K1500 Silverado 1991 Chevrolet K1500 Sport 1990-1998 Chevrolet K1500 WT 1992-1999 Chevrolet K1500 Suburban Base 1995-1999 Chevrolet K1500 Suburban LS 1995-1997,1999 Chevrolet K1500 Suburban LT 1992-1994 Chevrolet K1500 Suburban Silverado 1977-1981 Chevrolet K20 Cheyenne 1981-1986 Chevrolet K20 Custom 1977-1980 Chevrolet K20 Custom Deluxe 1981 Chevrolet K20 Deluxe 1977-1986 Chevrolet K20 Scottsdale 1977-1983,1985-1986 Chevrolet K20 Silverado 1981-1986 Chevrolet K20 Suburban Custom 1977-1980 Chevrolet K20 Suburban Custom Deluxe 1981 Chevrolet K20 Suburban Deluxe 1977-1980,1982,1984-1986 Chevrolet K20 Suburban Scottsdale 1977,1979-1980,1982-1983,1985-1986 Chevrolet K20 Suburban Silverado 1977-1980 Chevrolet K5 Blazer Cheyenne 1981-1986 Chevrolet K5 Blazer Custom 1977-1980 Chevrolet K5 Blazer Custom Deluxe 1981 Chevrolet K5 Blazer Deluxe 1984 Chevrolet K5 Blazer Scottsdale 1978,1980-1986 Chevrolet K5 Blazer Silverado 1989-1994 Chevrolet S10 Blazer Base 1989 Chevrolet S10 Blazer High Country 1994 Chevrolet S10 Blazer LT 1989-1990,1992 Chevrolet S10 Blazer Sport 1990-1994 Chevrolet S10 Blazer Tahoe 1991-1994 Chevrolet S10 Blazer Tahoe LT 1995-2001,2006 Chevrolet Tahoe Base 2008 Chevrolet Tahoe Hybrid 2000 Chevrolet Tahoe Limited 1995-2008 Chevrolet Tahoe LS 1995-2008 Chevrolet Tahoe LT 2007-2008 Chevrolet Tahoe LTZ 2007-2008 Chevrolet Tahoe PPV 2000,2002-2006 Chevrolet Tahoe Z71 2008 Chevrolet Trailblazer Base 2006-2007 Chevrolet Trailblazer LS 2006-2009 Chevrolet Trailblazer LT 2006-2009 Chevrolet Trailblazer SS 2006 Chevrolet Trailblazer EXT LS 2006 Chevrolet Trailblazer EXT LT 2015 GMC Canyon Base 2006-2008,2015 GMC Canyon SL 2006-2012,2015 GMC Canyon SLE 2006-2012,2015 GMC Canyon SLT 2006-2012 GMC Canyon WT 1977-1991 GMC Jimmy Base 1977-1985 GMC Jimmy High Sierra 1977-1990 GMC Jimmy Sierra Classic 1977-1982 GMC Jimmy Sierra Grande 1978-1982 GMC Jimmy Street Coupe 1977-1978 GMC K15 Base 1977-1978 GMC K15 High Sierra 1977 GMC K15 Indy Hauler 1977-1978 GMC K15 Sierra Classic 1977-1978 GMC K15 Sierra Grande 1977-1978 GMC K15 Suburban Base 1977-1978 GMC K15 Suburban High Sierra 1977-1978 GMC K15 Suburban Sierra Classic 1977-1978 GMC K15 Suburban Sierra Grande 1977-1978 GMC K25 Base 1977-1978 GMC K25 High Sierra 1977-1978 GMC K25 Sierra Classic 1977-1978 GMC K25 Sierra Grande 1977-1978 GMC K25 Suburban Base 1977-1978 GMC K25 Suburban High Sierra 1977-1978 GMC K25 Suburban Sierra Classic 1977-1978 GMC K25 Suburban Sierra Grande 1989-1991 GMC V1500 Suburban Base 1989 GMC V1500 Suburban Sierra Classic 1990 GMC V1500 Suburban SLE 1989-1991 GMC V2500 Suburban Base 1989 GMC V2500 Suburban Sierra Classic 1990 GMC V2500 Suburban SLE 2008-2010 Hummer H3 Alpha 2006-2010 Hummer H3 Base 2009 Hummer H3 Championship Series 2007-2009 Hummer H3 X ## Details -
