The ARB Air Locker for Dana 70/80 (37-spline, high-speed, 1.60-inch shaft) is a pneumatically actuated locker built for reliable, on-demand traction. Controlled from the cab, it locks both axle shafts to the ring gear for maximum grip and reverts to open-differential behavior when disengaged. The kit includes the Air Locker, activation switch, solenoid valve, air line and bulkhead fitting. Engineered with minimal moving parts, a two-piece construction and a steel-reinforced elastomer seal for extreme temperatures; operation requires an external air compressor (sold separately).
