Description
The ARB Air Locker Differential for Dana M220 & M210 Axles (model arbRD245) is the world’s premier traction aid engineered to keep you moving in all conditions. With a simple flick of a switch, the Air Locker provides instant, reliable locking at any speed, allowing you to conquer the toughest terrain with ease.
The key to its advantage lies in the pneumatically operated locking system inside the differential. When activated, it locks the internal differential gears, preventing the axle shafts from turning independently. This forces both wheels to rotate together, tied directly to the ring gear, delivering maximum traction at all times. When disengaged, the differential operates as a conventional open differential, preserving drivability.
The ARB Air Locker’s ultra-durable two-piece steel design has minimal moving parts, ensuring maximum reliability and strength. It features a patented timed locking mechanism for high strength and ultra-fast unlocking, and a steel-reinforced elastomer bonded annular seal designed to withstand extreme temperatures worldwide. The kit includes the Air Locker differential, activation switch, solenoid valve, airline, and bulkhead fitting. (Air compressor required for operation, sold separately.)
