The ARB Dana 44 Air Locker is the premium option in on-demand traction. ARB air lockers provide maximum traction for the most demanding off-road situations. ARB Air Lockers use a pneumatically controlled locking mechanism to switch between an open carrier and a fully locked differential. Once installed, all it takes is the simple flip of a switch to go from an open differential that works well on the street to a spool that provides 100% traction to both wheels off-road. ARB Air Lockers are currently available in over 100 configurations to suit a wide range of 4x4 vehicles from around the world and can be installed in both the front and rear axles.
Durability: ARB Air Lockers are sold in over 80 countries and there are over 150,000 units currently in use worldwide in both military and civilian applications. The secret to their success and reliability is that each ARB locker is designed and tested beyond the breaking point of standard and aftermarket axles such that your axles will break before causing any damage to the air locker.
How they work:
ARB lockers are fully selectable, air driven pneumatic locking differentials that can be powered by a 12v compressor or other source of on-board air.
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.
Included in the box:
Replacement differential, activation switch, solenoid valve, air line and bulkhead fittings.
The ARB Dana 44 air locker RD117 for your 30 spline axle for 3.73 & down gear ratios, can instantly lock differentials and allow you to tackle the toughest off-road terrain. The world's best traction aid, ARB Air Lockers keep you moving in all conditions.
Air Lockers from ARB are currently available in over 100 configurations to suit a wide range of off-road and 4x4 vehicles from around the world. Because the Dana 44 ARB® #RD117 air locker is only engaged when needed, it can be installed in both the front and rear axles, with separate switches independently controlling the RD117 air locker from within the off-road truck or vehicle.
