ARB is an Australian off-road accessories manufacturer founded in 1975 by Tony Brown in Melbourne, starting out with hand-fabricated roof racks and bull bars. In the late 1980s ARB acquired the Old Man Emu suspension brand and introduced the Air Locker to the American market.

This collection covers ARB's Air Locker selectable differential lockers -- pneumatic, driver-activated units that lock 100% on demand and unlock for normal driving -- across an extensive range of fitments including Jeep Dana 30/35/44, Toyota, Nissan, Ford 9" and 8.8", GM 10.5" 14-bolt, and Suzuki axles, plus ARB's single- and twin-motor 12V/24V onboard air compressors (CKMA12, CKMTA12, CKMTA24).
