Shaft Spline 35 - Low Speed - Dana 70/80 With our improved two piece design available right across the range, along with the addition of forged gears and an industry leading five year warranty, ARB Air Lockers are now better built and better backed than ever before. Created to provide 100 percent traction on demand, without sacrificing any of your vehicles highway driving performance, ARB Air Lockers employ a 12 volt ARB Air Compressor designed to activate (and deactivate) a solid and durable locking mechanism inside the differential. This gives you the traction you need, when you need it, all at the flip of a switch and all within the comfort of the drivers seat. The advantage of the ARB Air Locker lies in the pneumatically operated locking system inside the differential. When activated, the Air Locker prevents the 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 just like a conventional open differential. In addition to providing outright improvements to a 4x4s off road capabilities, the Air Locker offers significant environmental benefits. 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.
