The ARB Air Locker for AMC Model 20 (2.73 ratio and down) is a pneumatic differential locker that provides instant traction when engaged from the cab. It locks internal gears to tie both axle shafts to ring gear rotation for maximum grip, then reverts to open-differential behavior when disengaged. The kit includes the Air Locker, activation switch, solenoid valve, air line and bulkhead fitting. Constructed with minimal moving parts and a steel-reinforced elastomer seal for durability; an air compressor is required and sold separately.
