The ARB Air Locker for AMC Model 20 (29-spline, 3.08 ratio and up, 8 7/8-inch ring gear) is a pneumatically actuated differential locker that supplies immediate, full traction when engaged. Operable from inside the vehicle, it locks axle shafts together to maximize grip and returns to normal differential operation when released. The kit includes the Air Locker, activation switch, solenoid valve, air line and bulkhead fitting. Two-piece construction, minimal moving parts and a steel-reinforced elastomer seal help ensure longevity; an air compressor is required separately.
