ARB Air Locker Differential for Dana 44 with 35-Spline Shafts – 3.73 Ratio and Down

The world's premier traction aid, an ARB Air Locker(TM) keep you moving in all conditions. With the flick of the switch an Air Locker gives instant lock at any moment and its super strong design allows activation at any speed allowing you to tackle the toughest terrain. The advantage of the Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the internal differential gears from rotating and therefore prevents the axle shafts from turning independently of each other. With both wheels tied directly to the rotation of the ring gear, the vehicle maintains maximum possible traction at all times. When unlocked, it operates like a conventional open differential. An Air Locker equipped vehicle can be driven in a slower, safer and more controlled manner, greatly reducing the likelihood of vehicle damage and environmental impact.

The ARB Air Locker Differential (Part Number RD147) offers unparalleled traction control for your vehicle, especially in challenging off-road conditions. Designed for Dana 44 axles with 35-spline shafts and a gear ratio of 3.73 and down, this pneumatic locking system provides instant engagement at the flick of a switch, allowing you to tackle difficult terrain with confidence. Its robust construction and innovative design enable activation at any speed, making it ideal for extreme driving scenarios while maintaining on-road drivability. When engaged, the Air Locker prevents internal differential gears from turning independently, locking both wheels together and ensuring maximum traction on demand. When disengaged, it functions as a standard open differential, providing smooth on-road operation and reducing driveline wear. The system's pneumatic operation ensures quick locking and unlocking, thanks to a patented timed mechanism that offers high strength and ultra-fast response times. This setup not only enhances off-road capability but also promotes safer driving by reducing the risk of vehicle damage and environmental impact. The kit includes the differential, activation switch, solenoid valve, air line, and bulkhead fitting, offering a comprehensive solution for your vehicle's traction needs. Its steel-reinforced, elastomer-bonded annular seal withstands extreme climatic temperatures, ensuring durability in harsh environments. The two-piece design emphasizes strength and reliability, with minimal moving parts to reduce potential failure points. An air compressor is required for operation and sold separately, providing flexibility for installation. Ideal for enthusiasts seeking maximum control and dependability, the ARB Air Locker Differential ensures superior traction and confidence during off-road adventures, without compromising on-road comfort or safety.
