ARB Air Locker for 1972-2006 Dana 30 27 Spline 3.73 & Up Ratio Fits: CJ/XJ/YJ/TJ/ZJ/WJ - Newer vehicles with limited slip differentials (LSDs), etc may offer some improvement over standard differentials, but more often you'll find the slipping is not "limited" enough to maintain forward progress. Auto locking differentials also have their disadvantages. Aside from being noisy, they often upset the on highway and off road driving characteristics of your 4x4. During normal driving conditions, vehicle responsiveness becomes less predictable, and when highway surfaces become wet or icy, the driver must use extreme caution just to keep the truck in control. - THE SOLUTION - ARB has been challenging conventional thinking on off road equipment designs for over 30 years, and the ARB Air Locker has been a success from the very beginning. Created to provide 100% traction on demand, without sacrificing any of your vehicle's highway driving performance, ARB Air Lockers employ a 12 volt 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 flick of a switch, all within the safety and comfort of the driver's 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 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 conventional "open" differentials. When approaching difficult terrain, less reliance is put on momentum. An Air Locker equipped truck can be driven in a slower, safer and more controlled manner as a result of vastly improved traction. This style of driving greatly reduces the likelihood of incurring vehicle damage and lessens the environmental impact as well.
